ART: Log all monitor operations to systrace
Add a VLOG option ("-verbose:systrace-locks") to log all monitor
operations to systrace. This requires non-fastpath thread
entrypoints, and ATRACE tags for locking and unlocking.
Do a bit of cleanup to the entrypoint initialization to share
common setup.

Add an ImtConflictTable to better resolve IMT conflicts.
- Attach a ImtConflictTable to conflict runtime ArtMethod.
- Initially 0, a new one will be created at the first hit of
the conflict method.
- If the assembly code does not find a target method in the table,
we will create a new one again, copying the data from the previous
table and adding the new mapping.
Implemented for arm/arm64/x86/x64.

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 Baker's read barrier fast path implementation.
Introduce an x86 fast path implementation in Optimizing for
Baker's read barriers (for both heap reference loads and GC
root loads). The marking phase of the read barrier is
performed by a slow path, invoking a new runtime entry point
(artReadBarrierMark).
Other read barrier algorithms continue to use the original
slow path based implementation, which has been renamed as
GenerateReadBarrierSlow/GenerateReadBarrierForRootSlow.

lambda: Add support for invoke-interface for boxed innate lambdas
Lambda closures created with the 'create-lambda' instruction
(termed "innate lambdas") can be turned into an object with 'box-lambda'.
This CL enables support for those kinds of lambdas to work with
'invoke-interface' by generating a proxy class for the lambda.
Note: MIPS32/64 support not included.

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).

Rosalloc fast path in assembly for x86_64.
Measurements (host, ms)
BinaryTrees: 324 -> 360 (+11%)
BinaryTrees with 64 MB alloc stack + 1 GB heap:
299 -> 275 (-8%)
MemAllocTest: 414 -> 368 (-11%)
Interestingly, BinaryTrees gets slower with default settings due to more
blocking (gc-for-alloc) collections. It seems because allocations are
faster, the allocation stack size and the heap size become the
bottleneck (note both an allocation stack overflow as well as heap
exhaustion cause gc-for-alloc collections). With a larger allocation
stack and heap where no blocking collections are observed, BinaryTrees
gets faster.

ART: Remove some of the Mac craziness
We rely on new-enough Clang/LLVM builds nowadays. The integrated
assembler supports named parameters. Throw away most of the
old duplication (effectively cutting support for older Clang
versions). The only required duplications are:
1) Clang as does not support .altmacro. However, the Clang
preprocessor works different wrt/ the GCC preprocessor
and does not give us trouble with inserted spaces.
2) On the Mac, symbols are prefixed with an underscore.
This should help to avoid breaking the Mac build when changing
the assembly code, and prepare for a complete Clang-only build
for x86 and x86-64. Switching to the integrated assembler for
the host build may be done in a follow-up CL.

Now we properly compare the size of the image space against the size
of the image file.

[MIPS64] Fix art_quick_invoke_stub argument offsets.

Move mirror::ArtMethod to native
Optimizing + quick tests are passing, devices boot.
TODO: Test and fix bugs in mips64.
Saves 16 bytes per most ArtMethod, 7.5MB reduction in system PSS.
Some of the savings are from removal of virtual methods and direct

Replace String CharArray with internal uint16_t array.
Summary of high level changes:
- Adds compiler inliner support to identify string init methods
- Adds compiler support (quick & optimizing) with new invoke code path
that calls method off the thread pointer
- Adds thread entrypoints for all string init methods
- Adds map to verifier to log when receiver of string init has been
copied to other registers. used by compiler and interpreter

Remove ArtMethod* parameter from dex cache entry points.
Load the ArtMethod* using an optimized stack walk instead.
This reduces the size of the generated code.
Three of the entry points are called only from a slow-path
and the fourth (InitializeTypeAndVerifyAccess) is rare and
already slow enough that the one or two extra loads
(depending on whether we already have the ArtMethod* in a
register) are insignificant. And as we're starting to use
PC-relative addressing of the dex cache arrays (already
done by Quick for the boot image), having the ArtMethod* in
a register becomes less likely anyway.

Refactor and improve GC root handling
Changed GcRoot to use compressed references. Changed root visiting to
use virtual functions instead of function pointers. Changed root visting
interface to be an array of roots instead of a single root at a time.
Added buffered root marking helper to avoid dispatch overhead.
Root marking seems a bit faster on EvaluateAndApplyChanges due to batch
marking. Pause times unaffected.
Mips64 is untested but might work, maybe.

Deoptimization-based bce.
A mechanism is introduced that a runtime method can be called
from code compiled with optimizing compiler to deoptimize into
interpreter. This can be used to establish invariants in the managed code
If the invariant does not hold at runtime, we will deoptimize and continue
execution in the interpreter. This allows to optimize the managed code as
if the invariant was proven during compile time. However, the exception
will be thrown according to the semantics demanded by the spec.
The invariant and optimization included in this patch are based on the
length of an array. Given a set of array accesses with constant indices
{c1, ..., cn}, we can optimize away all bounds checks iff all 0 <= min(ci) and
max(ci) < array-length. The first can be proven statically. The second can be
established with a deoptimization-based invariant. This replaces n bounds
checks with one invariant check (plus slow-path code).

Don't copy fill array data to quick literal pool.
Currently quick copies the fill array data from the dex file to the literal
pool. It then has to go through hoops to pass this PC relative address down
to out-of-line code. Instead, pass the offset of the table to the out-of-line
code and use the CodeItem data associated with the ArtMethod. This reduces
the size of oat code while greatly simplifying it.
Unify the FillArrayData implementation in quick, portable and the interpreters.

Reduce stack usage for overflow checks
This reduces the stack space reserved for overflow checks to 12K, split
into an 8K gap and a 4K protected region. GC needs over 8K when running
in a stack overflow situation.
Also prevents signal runaway by detecting a signal inside code that
resulted from a signal handler invokation. And adds a max signal count to
the SignalTest to prevent it running forever.
Also reduces the number of iterations for the InterfaceTest as this was
taking (almost) forever with the --trace option on run-test.

This combines the x86 and x86_64 fault handlers into one. It also
merges in the change to the entrypoints for X86_64.
Replaces generic instruction length calculator with one that only
works with the specific instructions we use.

Reduce stack usage for overflow checks
This reduces the stack space reserved for overflow checks to 12K, split
into an 8K gap and a 4K protected region. GC needs over 8K when running
in a stack overflow situation.
Also prevents signal runaway by detecting a signal inside code that
resulted from a signal handler invokation. And adds a max signal count to
the SignalTest to prevent it running forever.
Also reduces the number of iterations for the InterfaceTest as this was
taking (almost) forever with the --trace option on run-test.

ART: Use StackReference in Quick Stack Frame
The method reference at the bottom of a quick frame is a stack
reference and not a native pointer. This is important for 64b
architectures, where the notions do not coincide.
Change key methods to have StackReference<mirror::ArtMethod>*
parameter instead of mirror::ArtMethod**. Make changes to
invoke stubs for 64b archs, change the frame setup for JNI code
(both generic JNI and compilers), tie up loose ends.
Tested on x86 and x86-64 with host tests. On x86-64, tests succeed
with jni compiler activated. x86-64 QCG was not tested.

Add "arch_test" gtest for assembly stub constants, add some ARM64 assembly code
Add a test that (1) checks all callee-save method frame sizes for
all architectures, (2) checks thread offsets for the runtime
architecture and (3) checks callee-save method offsets for the
runtime architecture.
The "asm_support_XXX.h" files now only contain definitions that are
common between all architectures. Architecture-specific definitions
(i.e., special registers names) have been pushed into the corresponding
.S file. This change was required to be able to undefine definitions
in the test, so that multiple tests can be written in one file.
Test (1) above is in a sense two-stage. The arch_test gtest compares
constants (if it finds them) against the frame size as reported by
the ArtMethods created by the Runtime. This works for all architectures
as we can provide the instruction-set to CreateCalleeSaveMethod. The
second stage of the "test" are preprocessor tests with "#error" in the
case that the constants are not the expected value.
Optimally I'd like to change that to an actual runtime test exercising
the assembly code, which would also allow to check whether the right
registers are stored.
Also added missing assembly code for ARM64 for the callee-save macros.
Also fix X86_64 compilation for Clang 3.5.

Add a GTest for Assembly Stubs, Add some ARM64 and X86-64 Stubs
This GTest adds some runtime testing for the stubs that does not
rely on the compiler. This should allow to add or update the stubs
and do testing, especially on architectures without working compiler.
This test is a bit dangerous: if it doesn't know how to handle an
architecture, it will only log a warning. This is so that testing
does not break at the moment. The warning is forced to stdout, too,
so that it is always visible.
Add art_quick_check_cast to ARM64 and X86-64. Add art_quick_memcpy
to X86-64. The latter should be removed in a good compiler, as it is
practically only overhead. Add minor CFI information in ARM.

Generic JNI implementation for x86_64
Starting implementation for generic JNI on x86_64. Frames are of
large static size (>4K) right now, should be compacted later. Passes
the whole of jni_compiler_test.

Initial changes towards Generic JNI option
Some initial changes that lead to an UNIMPLEMENTED. Works
by not compiling for JNI right now and tracking native methods
which have neither quick nor portable code. Uses new trampoline.

Work in the direction of hard float quick ABIs.
Pass a shorty to ArtMethod::Invoke so that register setup can use it.
Document x86-64 ABI.
Add extra debug output for one JNI native method registration fails, namely a
dump of the Class and its dex file's location.
Add hack to get testing of OatMethod's without GC maps working in 64bit.

Object model changes to support 64bit.
Modify mirror objects so that references between them use an ObjectReference
value type rather than an Object* so that functionality to compress larger
references can be captured in the ObjectRefererence implementation.
ObjectReferences are 32bit and all other aspects of object layout remain as
they are currently.
Expand fields in objects holding pointers so they can hold 64bit pointers. Its
expected the size of these will come down by improving where we hold compiler
meta-data.
Stub out x86_64 architecture specific runtime implementation.
Modify OutputStream so that reads and writes are of unsigned quantities.
Make the use of portable or quick code more explicit.
Templatize AtomicInteger to support more than just int32_t as a type.
Add missing, and fix issues relating to, missing annotalysis information on the
mutator lock.
Refactor and share implementations for array copy between System and uses
elsewhere in the runtime.
Fix numerous 64bit build issues.
