Use a flag from the verifier to know if we should compile.
Only used for the lack of bottom type in the aget-object case
for now. Could be used for more.

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
methods object arrays.

Quick: Abolish kMirOpCheckPart2.
The tricks played with kMirOpCheckPart2 are making the
native GC map generation unnecessarily complex. They have
caused problems in the past and now there is bad interaction
with the DCE. Rather than fixing it time and again, remove
the pseudo-insn.
(The whole purpose of those tricks seems to be to allow the
register tracking to be used for the throwing insn before
resetting the tracking for the next block. However, it's
questionable whether that's better than processing the
throwing insn with the subsequent instructions.)

Fixed layout for dex caches in boot image.
Define a fixed layout for dex cache arrays (type, method,
string and field arrays) for dex caches in the boot image.
This gives those arrays fixed offsets from the boot image
code and allows PC-relative addressing of their elements.
Use the PC-relative load on arm64 for relevant instructions,
i.e. invoke-static, invoke-direct, const-string,
const-class, check-cast and instance-of. This reduces the
arm64 boot.oat on Nexus 9 by 1.1MiB.
This CL provides the infrastructure and shows on the arm64
the gains that we can achieve by having fixed dex cache
arrays' layout. To fully use this for the boot images, we
need to implement the PC-relative addressing for other
architectures. To achieve similar gains for apps, we need
to move the dex cache arrays to a .bss section of the oat
file. These changes will be implemented in subsequent CLs.
(Also remove some compiler_driver.h dependencies to reduce
incremental build times.)

Add JIT
Currently disabled by default unless -Xjit is passed in.
The proposed JIT is a method JIT which works by utilizing interpreter
instrumentation to request compilation of hot methods async during
runtime.
JIT options:
-Xjit / -Xnojit
-Xjitcodecachesize:N
-Xjitthreshold:integervalue
The JIT has a shared copy of a compiler driver which is accessed
by worker threads to compile individual methods.
Added JIT code cache and data cache, currently sized at 2 MB
capacity by default. Most apps will only fill a small fraction of
this cache however.
Added support to the compiler for compiling interpreter quickened
byte codes.
Added test target ART_TEST_JIT=TRUE and --jit for run-test.
TODO:
Clean up code cache.
Delete compiled methods after they are added to code cache.
Add more optimizations related to runtime checks e.g. direct pointers
for invokes.
Add method recompilation.
Move instrumentation to DexFile to improve performance and reduce
memory usage.

Quick: Disable DCE until we fix FP/Core reg mismatches.
GVN and TypeInference can miss some FP/Core register
mismatch:
const v0, #X ; marked as float
invoke-virtual v0, void foo(float)
const v0, #X ; marked as core
aput v0, v1, v2 ; float[] not used
The second const is eliminated by the DCE because it writes
the same value to the same dalvik reg. We replace the SSA
register name defined by the first const and used by the
invoke-virtual with the one defined by the second const.
When we generate code for the invoke-virtual, we get a core
location and may need a temporary to set up the FP argument
and we may not have an available temporary.
This may affect the bug below (more investigation needed).

ART: Added Checker, a pattern matching test engine
This patch adds a Python script which implements a domain-specific
mini-language similar to that of LLVM's FileCheck. It is primarily
intended for writing tests for the optimizing compiler but could be
configured for other use cases too. It is implemented from scratch in
order to avoid dependency on LLVM.
Checker tests are written in Java and dex2oat is invoked with a flag
which dumps the CFG before and after each pass of the optimizing
compiler. The output is then compared against assertions in the
test's comments parsed by Checker. See comments in tools/checker.py
for more details about the currently supported language features.
This initial CL implements only one type of assertion - whether the
output contains lines matching a desired pattern in the given order -
but supports both plain text and regex matching and allows for
equivalency testing by matching for the outcome of a previous match.
See the tests in compiler/optimizing/test/ConstantFolding.java for
examples.

Remove -Wno-unused-parameter and -Wno-sign-promo from base cflags.
Fix associated errors about unused paramenters and implict sign conversions.
For sign conversion this was largely in the area of enums, so add ostream
operators for the effected enums and fix tools/generate-operator-out.py.
Tidy arena allocation code and arena allocated data types, rather than fixing
new and delete operators.
Remove dead code.

ARM: Use hardfp calling convention between java to java call.
This patch default to use hardfp calling convention. Softfp can be enabled
by setting kArm32QuickCodeUseSoftFloat to true.
We get about -1 ~ +5% performance improvement with different benchmark
tests. Hopefully, we should be able to get more performance by address the left
TODOs, as some part of the code takes the original assumption which is not
optimal.
DONE:
1. Interpreter to quick code
2. Quick code to interpreter
3. Transition assembly and callee-saves
4. Trampoline(generic jni, resolution, invoke with access check and etc.)
5. Pass fp arg reg following aapcs(gpr and stack do not follow aapcs)
6. Quick helper assembly routines to handle ABI differences
7. Quick code method entry
8. Quick code method invocation
9. JNI compiler
TODO:
10. Rework ArgMap, FlushIn, GenDalvikArgs and affected common code.
11. Rework CallRuntimeHelperXXX().

ART: Change temporaries to positive names
Changes compiler temporaries to have positive names. The numbering now
puts them above the code VRs (locals + ins, in that order). The patch also
introduces APIs to query the number of temporaries, locals and ins.
The compiler temp infrastructure suffered from several issues
which are also addressed by this patch:
-There is no longer a queue of compiler temps. This would be polluted
with Method* when post opts were called multiple times.
-Sanity checks have been added to allow requesting of temps from BE
and to prevent temps after frame is committed.
-None of the structures holding temps can overflow because they are
allocated to allow holding maximum temps. Thus temps can be requested
by BE with no problem.
-Since the queue of compiler temps is no longer maintained, it is no
longer possible to refer to a temp that has invalid ssa (because it
was requested before ssa was run).
-The BE can now request temps after all ME allocations and it is guaranteed
to actually receive them.
-ME temps are now treated like normal VRs in all cases with no special
handling. Only the BE temps are handled specially because there are no
references to them from MIRs.
-Deprecated and removed several fields in CompilationUnit that saved
register information and updated callsites to call the new interface from
MIRGraph.

Reduced memory usage of primitive fields smaller than 4-bytes
Reduced memory used by byte and boolean fields from 4 bytes down to a
single byte and shorts and chars down to two bytes. Fields are now
arranged as Reference followed by decreasing component sizes, with
fields shuffled forward as needed.

compilers, hide some compiler specifics, lower global includes.
