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.
