Clean up OatQuickMethodHeader after Quick removal.
This reduces the size of the pre-header by 8 bytes, reducing
oat file size and mmapped .text section size. The memory
needed to store a CompiledMethod by dex2oat is also reduced,
for 32-bit dex2oat by 8B and for 64-bit dex2oat by 16B. The
aosp_flounder-userdebug 32-bit and 64-bit boot.oat are each
about 1.1MiB smaller.
Disable the broken StubTest.IMT, b/27991555 .

Reduce memory used by CompiledMethods.
Use LengthPrefixedArray<>s instead of SwapVector<>s to store
CompiledMethod data and get rid of the unnecessary members
of CompiledMethod to reduce dex2oat memory usage. Refactor
the deduplication from CompilerDriver to a new class.
Use HashSet<> instead of std::set<> for the DedupeSet<> to
further decrease the memory usage and improve performance.
This reduces the dex2oat memory usage when compiling boot
image on Nexus 5 (with Optimizing, -j1) by ~6.75MiB (5%).
This also reduces the compile time by ~2.2% (~1.6% dex2oat
time; with Optimizing, without -j).

ART stack unwinding fixes for libunwind/gdb/lldb.
dex2oat can already generate unwinding and symbol information which
allows tools to create backtrace of mixed native and Java code.
This is a cherry pick from aosp/master which fixes several issues.
Most notably:
* It enables generation of ELF-64 on 64-bit systems (in dex2oat, C
compilers already produce ELF-64). Libunwind requires ELF-64 on
64-bit systems for backtraces to work.
* It enables loading of ELF files with dlopen. This is required for
libunwind to be able to generate backtrace of current process (i.e.
the process requesting backtrace of itself).
* It adds unit test to test the above (32 vs 64 bit, in-proces vs
out-of-process, application code vs framework code).
* Some other fixes or clean-ups which should not be of much
significance but which are easier to include to make the
important CLs cherry-pick cleanly.
This is squash of the following commits from aosp/master:

Add --generate-debug-info flag and remove the other two flags.
Replace the flags --include-debug-symbols and --include-cfi
with single flag called --generate-debug-info (with alias -g).
The name "symbol" was not ideal, since depending on context it
may be interpreted as "ELF symbols", or "debugging information".
This CL also means that we have only the options to include
either all debugging information or none. This should be fine,
since we can use standard tools to strip anything we do not want.

Improve performance of invokevirtual/invokeinterface with embedded imt/vtable
Add an embedded version of imt/vtable into class object. Both tables start at
fixed offset within class object so method/entry point can be loaded directly
from class object for invokeinterface/invokevirtual.

Thumb2 assembler for JNI compiler and optimizing compiler
This provides a programmatic assembler for the thumb2 instruction set for
ARM. The interface is the same as the ARM assembler and the ARM assembler has
been moved into Arm32Assembler. The assembler handles most 16 and 32 bit instructions
and also allows relocations due to branch expansion. It will also rewrite cbz/cbnz
instructions if they go out of range.
It also changes the JNI compiler to use the thumb2 assembler as opposed
to forcing it to use ARM32. The trampoline compiler still uses ARM due to the
way it returns the address of its generated code. A trampoline in thumb2 is the
same size as that in ARM anyway (8 bytes).
Provides gtest for testing the thumb2 instruction output. This gtest only runs
on the host as it uses arm-eabi-objdump to disassemble the generated code. On the
target the output is not checked but the assembler will still be run to perform
all its checks.

Compatibility layer to transition from UniquePtr to std::unique_ptr.
Use ART_WITH_STLPORT (enabled for the target) to cause the use of UniquePtr,
for the host switch to std::unique_ptr. For now the type remains called
UniquePtr.
Make dalvik compile with clang on the host, move its build to C++11.

Add Handle/HandleScope and delete SirtRef.
Delete SirtRef and replaced it with Handle. Handles are value types
which wrap around StackReference*.
Renamed StackIndirectReferenceTable to HandleScope.
Added a scoped handle wrapper which wraps around an Object** and
restores it in its destructor.
Renamed Handle::get -> Get.

Give Compiler a back reference to the driver.
The compiler driver is a single object delegating work to the compiler, rather
than passing it through to every Compiler call make it a member of Compiler so
that it maybe queried. This simplifies the Compiler API and makes the
relationship to CompilerDriver more explicit.
Remove reference arguments that contravene code style.

ART: aarch64 jni compiler needs to extend small return types
As aarch64 calling convention does not mandate extension on return
values anymore and leaves the upper bits undefined, the jni compiler
needs to sign- or zero-extend the returned values when necessary.
As three architectures need extension now, refactor this fact into a
flag into a virtual method.
Add tests to JniTest that exercise the required extension.

AArch64: Jni compiler fixes
This patch fixes some of the issues with the ARM64 assembler and JNI
compiler.
The JNI compiler is not enabled by default, yet. To enable, change
line 1884 in compiler/driver/compiler_driver.cc, removing kArm64 from
the GenericJNI list.
The compiler passes all tests in jni_compiler_test.
Also change the common_compiler_test instruction-set-features logic.
We allow tests when the build-time features are a subset of the
runtime features.
Dex2oat cross-compiling is now working. A 32b version of dex2oat should
be able to compile correctly.

x86_64: JNI compiler
Passed all tests from jni_compiler_test and art/test on host with jni_copiler.
Incoming argument spill is enabled, entry_spills refactored. Now each entry spill
contains data type size (4 or 8) and offset which should be used for spill.
Assembler REX support implemented in opcodes used in JNI compiler.
Please note, JNI compiler is not enabled by default yet (see compiler_driver.cc:1875).

Multi threaded hashed deduplication during compilation.

writer. This enables deduplication to be performed on multiple
threads. Also added a hash function to avoid excessive comparison
of byte arrays.

Entry point clean up.
Create set of entry points needed for image methods to avoid fix-up at load time:
- interpreter - bridge to interpreter, bridge to compiled code
- jni - dlsym lookup
- quick - resolution and bridge to interpreter
- portable - resolution and bridge to interpreter
Fix JNI work around to use JNI work around argument rewriting code that'd been
accidentally disabled.
Remove abstact method error stub, use interpreter bridge instead.
Consolidate trampoline (previously stub) generation in generic helper.
Simplify trampolines to jump directly into assembly code, keeps stack crawlable.
Dex: replace use of int with ThreadOffset for values that are thread offsets.
Tidy entry point routines between interpreter, jni, quick and portable.

Create separate Android.mk for main build targets
The runtime, compiler, dex2oat, and oatdump now are in seperate trees
to prevent dependency creep. They can now be individually built
without rebuilding the rest of the art projects. dalvikvm and jdwpspy
were already this way. Builds in the art directory should behave as
before, building everything including tests.
