ART: Clean up arm64 kNumberOfXRegisters usage.
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.
Bug: 13925192

Revert "Revert "ART: Implement X86 hard float (Quick/JNI/Baseline)""
This reverts commit 949c91fb91f40a4a80b2b492913cf8541008975e.
This time, don't clobber EBX before saving it.
Redo some of the macros to make register usage explicit.

ART: Implement X86 hard float (Quick/JNI/Baseline)
Use XMM0-XMM3 as parameter registers for float/double on X86. X86_64
already uses XMM0-XMM7 for parameters.
Change the 'hidden' argument register from XMM0 to XMM7 to avoid a
conflict.
Add support for FPR save/restore in runtime/arch/x86.
Minimal support for Optimizing baseline compiler.
Bump the version in runtime/oat.h because this is an ABI change.

Move quick frame info to OatQuickMethodHeader.
Rename OatMethodHeader to OatQuickMethodHeader, move frame
info from OatMethodOffsets to OatQuickMethodHeader. Retrieve
the info from other places for non-quick methods (portable
compiled bytecode or jni stub, generic jni, runtime,
abstract and proxy).
This change has a libcore/ companion CL
"Remove ArtMethod's quick fields for frame size and spills."
