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.

(cherry picked from commit e401d146407d61eeb99f8d6176b2ac13c4df1e33)

Change-Id: I622469a0cfa0e7082a2119f3d6a9491eb61e3f3d

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.

ART: Fix casts for 64-bit pointers on 32-bit compiler.

Fix JDWP tests after ArtMethod change

Fixes Throwable::GetStackDepth for exception event detection after
internal stack trace representation change.

Adds missing ArtMethod::GetInterfaceMethodIfProxy call in case of
proxy method.

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.

[MIPS64] Fix art_quick_invoke_stub argument offsets.

ArtMethod reference's size got bigger, so we need to move other args
and leave enough space for ArtMethod* and 'this' pointer.

This fixes mips64 boot.
