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.
