Change deoptimize entrypoint to save everything.
And implement FPU register retrieval from stack on x86.
On Nexus 9, AOSP ToT, the boot.oat size reduction is
prebuilt multi-part boot image:
- 32-bit boot.oat: -20KiB (-0.03%)
- 64-bit boot.oat: -45KiB (-0.06%)
on-device built single boot image:
- 32-bit boot.oat: -24KiB (-0.04%)
- 64-bit boot.oat: -36KiB (-0.05%)
Test: Run ART test suite on host and Nexus 9.
