ARM64: Improve Mterp. Several straight-forward optimizations: - use ubfx instead of SHR+AND, - do not mask shifting distance, - use 64-bit LDRSH to avoid subsequent sign extension, - use CBNZ instead of CMP+BNE for null checks, - style: use SXTW alias instead of explicit SBFM. Test: Run ART test suite on Nexus 9 with the interpreter. Change-Id: Ibcc11ce7f455432ecb789f727da21f269f8370f0
