Enable arm64 optimizations that exist for power/x86 (#3393)

Enable unaligned accesses on arm64

64-bit Arm platforms support unaligned accesses.

Running the string benchmarks this change improves performance
by an average of 1.04x, min .96x, max 1.21x, median 1.01x

arm64 enable gc optimizations

Similar to x86 and powerpc optimizations.
