Revert "Revert "Use implicit null checks inside try blocks.""
Fix implicit checks in try blocks to emit stack maps.
Fix arm64 null expection from signal entrypoint to call
the runtime handler instead or simply jumping there.
On Nexus 9, AOSP ToT, the boot.oat size reduction is
prebuilt multi-part boot image:
- 32-bit boot.oat: -448KiB (-1.3%)
- 64-bit boot.oat: -528KiB (-1.2%)
on-device built single boot image:
- 32-bit boot.oat: -448KiB (-1.4%)
- 64-bit boot.oat: -528KiB (-1.3%)
Note that the oat files no longer contain dex files which
have been moved to vdex, so the percentages are not directly
comparable with the those reported in the original commit.
Test: Run ART test suite including gc-stress on host and Nexus 9.

Use implicit null checks inside try blocks.
Make implicit null check entrypoint save all registers, use
platform-specific approach to still pass the fault address.
Allow implicit null checks in try blocks.
On Nexus 9, AOSP ToT, the boot.oat size reduction is
prebuilt multi-part boot image:
- 32-bit boot.oat: -452KiB (-0.7%)
- 64-bit boot.oat: -482KiB (-0.7%)
on-device built single boot image:
- 32-bit boot.oat: -444KiB (-0.7%)
- 64-bit boot.oat: -488KiB (-0.7%)
Test: Run ART test suite on host and Nexus 9.
Test: Build aosp_mips64-eng.

fault address within the lock word. Added tests to 439-npe.

Record implicit null checks at the actual invoke time.
ImplicitNullChecks are recorded only for instructions directly (see NB
below) preceeded by NullChecks in the graph. This way we avoid recording
redundant safepoints and minimize the code size increase.
NB: ParallalelMoves might be inserted by the register allocator between
the NullChecks and their uses. These modify the environment and the
correct action would be to reverse their modification. This will be
addressed in a follow-up CL.
