ARM64: Use link-time generated thunks for Baker CC read barrier.
Remaining work for follow-up CLs:
- array loads,
- volatile field loads,
- use implicit null check in field thunk.
Test: Added tests to relative_patcher_arm64
Test: New run-test 160-read-barrier-stress
Test: m test-art-target-gtest on Nexus 6P.
Test: testrunner.py --target on Nexus 6P.

Move Assemblers to the Arena.
And clean up some APIs to return std::unique_ptr<> instead
of raw pointers that don't communicate ownership.

Optimizing: Improve const-string code generation.
For strings in the boot image, use either direct pointers
or pc-relative addresses. For other strings, use PC-relative
access to the dex cache arrays for AOT and direct address of
the string's dex cache slot for JIT.
For aosp_flounder-userdebug:
- 32-bit boot.oat: -692KiB (-0.9%)
- 64-bit boot.oat: -948KiB (-1.1%)
- 32-bit dalvik cache total: -900KiB (-0.9%)
- 64-bit dalvik cache total: -3672KiB (-1.5%)
(contains more files than the 32-bit dalvik cache)
For aosp_flounder-userdebug forced to compile PIC:
- 32-bit boot.oat: -380KiB (-0.5%)
- 64-bit boot.oat: -928KiB (-1.0%)
- 32-bit dalvik cache total: -468KiB (-0.4%)
- 64-bit dalvik cache total: -1928KiB (-0.8%)
(contains more files than the 32-bit dalvik cache)

ART: Allow method references across oat files for multi-image, 2nd attempt.
These were disabled because we didn't have sufficient
information about the multi-image layout when processing
link-time patches in OatWriter. This CL refactors the
ELF file creation so that the information is available.
Also clean up ImageWriter to use oat file indexes instead
of filenames and avoid reopening the oat file to retrieve
the checksum.

Add DCHECKs to ArenaVector and ScopedArenaVector.
Implement dchecked_vector<> template that DCHECK()s element
access and insert()/emplace()/erase() positions. Change the
ArenaVector<> and ScopedArenaVector<> aliases to use the new
template instead of std::vector<>. Remove DCHECK()s that
have now become unnecessary from the Optimizing compiler.

Revert "Revert "ART: Implement literal pool for arm, fix branch fixup.""
This reverts commit fbeb4aede0ddc5b1e6a5a3a40cc6266fe8518c98.
Adjust block label positions. Bad catch block labels were the
reason for the revert.

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.

Fix some ArtMethod related bugs
Added root visiting for runtime methods, not currently required
since the GcRoots in these methods are null.
Added missing GetInterfaceMethodIfProxy in GetMethodLine, fixes
--trace run-tests 005, 044.
Fixed optimizing compiler bug where we used a normal stack location
instead of double on ARM64, this fixes the debuggable tests.
TODO: Fix JDWP tests.

Fix accidental IMT and root marking regression
Was always using the conflict trampoline. Also included fix for
regression in GC time caused by extra roots. Most of the regression
was IMT.
Fixed bug in DumpGcPerformanceInfo where we would get SIGABRT due to
detached thread.
EvaluateAndApplyChanges:
From ~2500 -> ~1980
GC time: 8.2s -> 7.2s due to 1s less of MarkConcurrentRoots

Fix bogus image test assert
Previously we were comparing the size of the non moving space to
size of the image file.
Now we properly compare the size of the image space against the size
of the image file.

Refactor RelativePatcher out of OatWriter.
Move the relative patcher classes to compiler/linker/ and
compiler/linker/<arch>/ . Refactor them to avoid OatWriter
dependency so that they can be unit tested. Add tests for
x86 and x86-64.
