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.
