Revert "Revert "Refactor HGraphBuilder and SsaBuilder to remove HLocals""
This patch merges the instruction-building phases from HGraphBuilder
and SsaBuilder into a single HInstructionBuilder class. As a result,
it is not necessary to generate HLocal, HLoadLocal and HStoreLocal
instructions any more, as the builder produces SSA form directly.
Saves 5-15% of arena-allocated memory (see bug for more data):
GMS 20.46MB => 19.26MB (-5.86%)
Maps 24.12MB => 21.47MB (-10.98%)
YouTube 28.60MB => 26.01MB (-9.05%)
This CL fixed an issue with parsing quickened instructions.

Build dominator tree before generating HInstructions
Second CL in the series of merging HGraphBuilder and SsaBuilder. This
patch refactors the builders so that dominator tree can be built
before any HInstructions are generated. This puts the SsaBuilder
removal of HLoadLocals/HStoreLocals straight after HGraphBuilder's
HInstruction generation phase. Next CL will therefore be able to
merge them.
This patch also adds util classes for iterating bytecode and switch
tables which allowed to simplify the code.

Pack stack map entries on bit level to save space.
Use only the minimum number of bits required to store stack map data.
For example, if native_pc needs 5 bits and dex_pc needs 3 bits, they
will share the first byte of the stack map entry.
The header is changed to store bit offsets of the fields rather than
byte sizes. Offsets also make it easier to access later fields without
calculating sum of all previous sizes.
All of the header fields are byte sized or encoded as ULEB128 instead
of the previous fixed size encoding. This shrinks it by about half.
It saves 3.6 MB from non-debuggable boot.oat (AOSP).
It saves 3.1 MB from debuggable boot.oat (AOSP).
It saves 2.8 MB (of 99.4 MB) from /system/framework/arm/ (GOOG).
It saves 1.0 MB (of 27.8 MB) from /system/framework/oat/arm/ (GOOG).
Field loads from stackmaps seem to get around 10% faster.
(based on the time it takes to load all stackmap entries from boot.oat)

Avoid generating dead code on frame enter/exit.
This includes stack operations and, on x86, call/pop to read PC.
bug=26997690
Rationale:
(1) If method is fully intrinsified, and makes no calls in slow
path or uses special input, no need to require current method.
(2) Invoke instructions with HasPcRelativeDexCache() generate code
that reads the PC (call/pop) on x86. However, if the invoke is
an intrinsic that is later replaced with actual code, this PC
reading code may be dead.
Example X86 (before/after):
0x0000108c: 83EC0C sub esp, 12
0x0000108f: 890424 mov [esp], eax <-- not needed
0x00001092: E800000000 call +0 (0x00001097)
0x00001097: 58 pop eax <-- dead code to read PC
0x00001098: F30FB8C1 popcnt eax, ecx
0x0000109c: F30FB8DA popcnt ebx, edx
0x000010a0: 03D8 add ebx, eax
0x000010a2: 89D8 mov eax, ebx
0x000010a4: 83C40C add esp, 12 <-- not needed
0x000010a7: C3 ret
0x0000103c: F30FB8C1 popcnt eax, ecx
0x00001040: F30FB8DA popcnt ebx, edx
0x00001044: 03D8 add ebx, eax
0x00001046: 89D8 mov eax, ebx
0x00001048: C3 ret
Example ARM64 (before/after):
0x0000103c: f81e0fe0 str x0, [sp, #-32]!
0x00001040: f9000ffe str lr, [sp, #24]
0x00001044: dac01020 clz x0, x1
0x00001048: f9400ffe ldr lr, [sp, #24]
0x0000104c: 910083ff add sp, sp, #0x20 (32)
0x00001050: d65f03c0 ret
0x0000103c: dac01020 clz x0, x1
0x00001040: d65f03c0 ret

Associate slow paths with the instruction that they belong to.
Almost all slow paths already know the instruction they belong to,
this CL just moves the knowledge to the base class as well.
This is needed to be be able to get the corresponding dex pc for
slow path, which allows us generate better native line numbers,
which in turn fixes some native debugging stepping issues.

Implement on-stack replacement for arm/arm64/x86/x86_64.
High-level overview:
- osr_method_threshold is used to know when to compile a method
in osr mode (-> treat all loops as irreducible).
- branch instructions in the compiler query whether they can
jump to an osr method.
- An osr entry point is found through the stack maps: if a stack
map is duplicated in the CodeInfo, it is an osr entry point.

x86/x86-64 read barrier support for concurrent GC in Optimizing.
This first implementation uses slow paths to instrument heap
reference loads and GC root loads for the concurrent copying
collector, respectively calling the artReadBarrierSlow and
artReadBarrierForRootSlow (new) runtime entry points.
Notes:
- This implementation does not instrument HInvokeVirtual
nor HInvokeInterface instructions (for class reference
loads), as the corresponding read barriers are not stricly
required with the current concurrent copying collector.
- Intrinsics which may eventually call (on slow path) are
disabled when read barriers are enabled, as the current
slow path infrastructure does not support this case.
- When read barriers are enabled, the code generated for a
HArraySet instruction always go into the array set slow
path for object arrays (delegating the operation to the
runtime), as we are lacking a mechanism to keep a
temporary register live accross a runtime call (needed for
the instrumentation of type checking code, which requires
two successive read barriers).

correct. We now actually construct the labels.

ART: Register allocation and runtime support for try/catch
This patch completes a series of CLs that add support for try/catch
in the Optimizing compiler. With it, Optimizing can compile all
methods containing try/catch, provided they don't contain catch loops.
Future work will focus on improving performance of the generated code.
SsaLivenessAnalysis was updated to propagate liveness information of
instructions live at catch blocks, and to keep location information on
instructions which may be caught by catch phis.
RegisterAllocator was extended to spill values used after catch, and
to allocate spill slots for catch phis. Catch phis generated for the
same vreg share a spill slot as the raw value must be the same.
Location builders and slow paths were updated to reflect the fact that
throwing an exception may not lead to escaping the method.
Instruction code generators are forbidden from using of implicit null
checks in try blocks as live registers need to be saved before handing
over to the runtime.
CodeGenerator emits a stack map for each catch block, storing locations
of catch phis. CodeInfo and StackMapStream recognize this new type of
stack map and store them separate from other stack maps to avoid dex_pc
conflicts.
After having found the target catch block to deliver an exception to,
QuickExceptionHandler looks up the dex register maps at the throwing
instruction and the catch block and copies the values over to their
respective locations.
The runtime-support approach was selected because it allows for the
best performance in the normal control-flow path, since no propagation
of catch phi values is necessary until the exception is thrown. In
addition, it also greatly simplifies the register allocation phase.
ConstantHoisting was removed from LICMTest because it instantiated
(now abstract) HConstant and was bogus anyway (constants are always in
the entry block).

Add more dwarf debug line info for Optimized methods.
Optimizing compiler generates minimum debug line info that
is built using the dex_pc information about suspend points.
This is not enough for performance and debugging needs.
This CL generates additional debug line information for
instructions which have known dex_pc and it ensures that
whole call sites are mapped (as opposed to suspend points
which map only one instruction past the function call).

ART: Add (Fpu)RegHigh stack map location kinds
When running Optimized code on 64-bit, high value of vreg pair may be
stored in the high 32 bits of a CPU register. This is not reflected in
stack maps which would encode both the low and high vreg as
kInRegister with the same register number, making it indistinguishable
from two non-wide vregs with the same value in the lower 32 bits.
Deoptimization deals with this by running the verifier and thus
obtaining vreg pair information, but this would be too slow for try/
catch. This patch therefore adds two new stack map location kinds:
kInRegisterHigh and kInFpuRegisterHigh to differentiate between the
two cases.
Note that this also applies to floating-point registers on x86.

Revert "Revert "ART: Implement try/catch blocks in Builder""
This patch enables the GraphBuilder to generate blocks and edges which
represent the exceptional control flow when try/catch blocks are
present in the code. Actual compilation is still delegated to Quick
and Baseline ignores the additional code.
To represent the relationship between try and catch blocks, Builder
splits the edges which enter/exit a try block and links the newly
created blocks to the corresponding exception handlers. This layout
will later enable the SsaBuilder to correctly infer the dominators of
the catch blocks and to produce the appropriate reverse post ordering.
It will not, however, allow for building the complete SSA form of the
catch blocks and consequently optimizing such blocks.
To this end, a new TryBoundary control-flow instruction is introduced.
Codegen treats it the same as a Goto but it allows for additional
successors (the handlers).
This reverts commit 3e18738bd338e9f8363b26bc895f38c0ec682824.

art::HInvoke and its subclasses can return the number of

Consequently, no longer remove a clinit check as last input
of a static invoke if it is still present during baseline
code generation, but ensure that static invokes have no such
check as last input in optimized compilations.

ART: Boolean simplifier
The optimization recognizes the negation pattern generated by 'javac'
and replaces it with a single condition. To this end, boolean values
are now consistently assumed to be represented by an integer.
This is a first optimization which deletes blocks from the HGraph and
does so by replacing the corresponding entries with null. Hence,
existing code can continue indexing the list of blocks with the block
ID, but must check for null when iterating over the list.

Unify ART's various implementations of bit_cast.
ART had several implementations of art::bit_cast:
1. one in runtime/base/casts.h, declared as:
template <class Dest, class Source>
inline Dest bit_cast(const Source& source);
2. another one in runtime/utils.h, declared as:
template<typename U, typename V>
static inline V bit_cast(U in);
3. and a third local version, in runtime/memory_region.h,
similar to the previous one:
template<typename Source, typename Destination>
static Destination MemoryRegion::local_bit_cast(Source in);
This CL removes versions 2. and 3. and changes their callers
to use 1. instead. That version was chosen over the others
as:
- it was the oldest one in the code base; and
- its syntax was closer to the standard C++ cast operators,
as it supports the following use:
bit_cast<Destination>(source)
since `Source' can be deduced from `source'.

Compress the Dex register maps built by the optimizing compiler.
- Replace the current list-based (fixed-size) Dex register
encoding in stack maps emitted by the optimizing compiler
with another list-based variable-size Dex register
encoding compressing short locations on 1 byte (3 bits for
the location kind, 5 bits for the value); other (large)
values remain encoded on 5 bytes.
- In addition, use slot offsets instead of byte offsets to
encode the location of Dex registers placed in stack
slots at small offsets, as it enables more values to use
the short (1-byte wide) encoding instead of the large
(5-byte wide) one.
- Rename art::DexRegisterMap::LocationKind as
art::DexRegisterLocation::Kind, turn it into a
strongly-typed enum based on a uint8_t, and extend it to
support new kinds (kInStackLargeOffset and
kConstantLargeValue).
- Move art::DexRegisterEntry from

runtime/stack_map.h and rename it as
art::DexRegisterLocation.
- Adjust art::StackMapStream,
art::CodeGenerator::RecordPcInfo,

- Implement unaligned memory accesses in art::MemoryRegion.
- Use them to manipulate data in Dex register maps.
- Adjust oatdump to support the new Dex register encoding.

redundant safepoints and minimize the code size increase.
NB: ParallalelMoves might be inserted by the register allocator between
the NullChecks and their uses. These modify the environment and the
correct action would be to reverse their modification. This will be

[optimizing compiler] Compute live spill size
The current stack frame calculation assumes that each live register to
be saved/restored has the word size of the machine. This fails for X86,
where a double in an XMM register takes up 8 bytes. Change the
calculation to keep track of the number of core registers and number of
fp registers to handle this distinction.
This is slightly pessimal, as the registers may not be active at the
same time, but the only way to handle this would be to allocate both
classes of registers simultaneously, or remember all the active
intervals, matching them up and compute the size of each safepoint
interval.

Implement double and float support for arm in register allocator.
The basic approach is:
- An instruction that needs two registers gets two intervals.
- When allocating the low part, we also allocate the high part.
- When splitting a low (or high) interval, we also split the high
(or low) equivalent.
- Allocation follows the (S/D register) requirement that low
registers are always even and the high equivalent is low + 1.

ART source line debug info in OAT files
OAT files have source line information enough for ART runtime needs like
jump to/from interpreter and thread suspension. But this information
is not enough for finer grained source level debugging and low-level
profiling (VTune or perf).
This patch adds to OAT files two additional sections:
.debug_line - DWARF formatted Elf32 section with detailed source line
information (mapping from native PC to Java source lines).
In addition to the debugging symbols added using the dex2oat option
--include-debug-symbols, the source line information is added to
the section .debug_line.
The source line info can be read by many Elf reading tools like objdump,
readelf, dwarfdump, gdb, perf, VTune, ...
gdb can use this debug line information in x86. In 64-bit mode
the information can be used if the oat file is mapped in the lower
address space (address has higher 32 bits zeroed). Relocation works.
Testing:
1. art/test/run-test --host --gdb [--64] 001-HelloWorld
2. in gdb: break Main.java:19
3. in gdb: break Runtime.java:111
4. in gdb: run - stops at void java.lang.Runtime.<init>()
5. in gdb: backtrace - shows call stack down to main()
6. in gdb: continue - stops at void Main.main() (only in 32-bit mode)
7. in gdb: backtrace - shows call stack down to main()
8. objdump -W <oat-file> - addresses are from VMA range of .text
section reported by objdump -h <file>
9. dwarfdump -ka <oat-file> - no errors expected
Size of aosp-x86-eng boot.oat increased by 11% from 80.5Mb to 89.2Mb
with two sections added .debug_line (7.2Mb) and .rel.debug (1.5Mb).
