Previously we recreated this intern table during runtime startup.
This added 50-100ms of boot time.
Fixed bug where we didn't copy over hashcodes into the image.
Deleted some stale code.

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 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.

Avoid undefined behavior for arm64 stemming from 1u << 32 in
loops with upper bound kNumberOfXRegisters.
Create iterators for enumerating bits in an integer either
from high to low or from low to high and use them for
<arch>Context::FillCalleeSaves() on all architectures.
Refactor runtime/utils.{h,cc} by moving all bit-fiddling
functions to runtime/base/bit_utils.{h,cc} (together with
the new bit iterators) and all time-related functions to
runtime/base/time_utils.{h,cc}. Improve test coverage and
fix some corner cases for the bit-fiddling functions.

Add linear alloc. Moved ArtField to be native object. Changed image
writer to put ArtFields after the mirror section.
Savings:
2MB on low ram devices
4MB on normal devices

* Images (.art) compiled with pic now have a new field added.
* isDexOptNeeded will now skip patch-ing for apps compiled PIC
* First-boot patching now only copies boot.art, boot.oat is linked
As a result, all system preopted dex files (with --compile-pic) no
longer take up any space in /data/dalvik-cache/<isa>.

Added more inlining, removed imt array allocation and replaced it
with a handle scope. Removed some un-necessary handle scopes.
Added logic to base interface method tables from the superclass so
that we dont need to reconstruct for every interface (large win).

Add a new executable called patchoat to art. This tool takes already
compiled images and oat files and changes their base address, acting as
a cheap form of relocation.
Add a --include-patch-information flag to dex2oat and code to add
required patch information to oat files created with the quick compiler.

The oat file is now always in the same directory, and has the
same name as the image file. Only difference is the extension.
This also removes the need for host-prefix.

We now create the image bitmap when we generate the image. The image
bitmap is written after the image inside of the image file. This
speeds up dex2oat by making walking the image during heap creation
unnecessary. This should also help memory pressure by enabling the
image bitmap to be swappable.

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.
