Optimizing: Better invoke-static/-direct dispatch.
Add framework for different types of loading ArtMethod*
and code pointer retrieval. Implement invoke-static and
invoke-direct calls the same way as Quick. Document the
dispatch kinds in HInvokeStaticOrDirect's new enumerations
MethodLoadKind and CodePtrLocation.
PC-relative loads from dex cache arrays are used only for
x86-64 and arm64. The implementation for other architectures
will be done in separate CLs.

This breaks the build for x86_64 targets. This is because on target the libvixl is not included as a
library for the libart.so target build. The build of non-x86_64 targets only works because the
compilers removes the dead-code that contains the libvixl symbols.

ART: Compress LengthPrefixedArray on 32-bit targets.
Previously, the LengthPrefixedArray<ArtMethod> on 32-bit
targets contained a 64-bit length field followed by the
ArtMethod elements with size only a multiple of 4, not 8.
Consequently, an odd-length array broke the alignment for
the following array which would have the 64-bit length
placed at an unaligned address.
To fix that, we make the length field 32-bit and explicitly
pass the alignment information to the LengthPrefixedArray.
This also makes the 32-bit boot image a bit smaller.
On Nexus 5, AOSP, ToT, the field section is 11528B smaller
and the method section is 21036B smaller. 64-bit targets
should see the same savings for the field section but no
difference for the methods section.

When checking on a null array, the cases of aput and aput-wide are

Make patchoat match offset when given a patched image
Previously if we gave patchoat a patched image and a already patched
(but improperly relocated) oat file it would not correctly patch the

Optimizing String.Equals as an intrinsic (x86_64)
The fourth implementation of String.Equals. I added an intrinsic
in x86_64 which is similar to the original java implementation
of String.equals: an instanceof check, null check,length check,
and reference equality check followed by a loop comparing strings
four characters at a time.
Interesting Benchmarking Values:
Optimizing Compiler on 64-bit Emulator
Intrinsic 1-5 Character Strings: 48 ns
Original 1-5 Character Strings: 56 ns
Intrinsic 1000+ Character Strings: 4009 ns
Original 1000+ Character Strings: 4704 ns
Intrinsic Non-String Argument: 35 ns
Original Non-String Argument: 42 ns

Change SS to use MarkObjectIfNotInToSpace for roots
The roots can be in the to-space since we may visit the declaring
class of an ArtMethod multiple times if it is on the call stack.
Fixes GSS/SS tests for a few test cases.
