See the comment-block at the top of Aarch64Assembler.cpp
for overview on how AArch64 support has been implemented
In addition, this commit contains
[x] AArch64 inline asm versions of gglmul series of
functions and a new unit test bench to test the
functions
[x] Assembly implementations of scanline_col32cb16blend
and scanline_t32cb16blend for AArch64, with unit
test bench
