Lasse Collin cd64dd70d5 liblzma: Use 8-byte method in memcmplen.h on ARM64. 
It requires fast unaligned access to 64-bit integers
and a fast instruction to count leading zeros in
a 64-bit integer (__builtin_ctzll()). This perhaps
should be enabled on some other archs too.

Thanks to Chenxi Mao for the original patch:
https://github.com/tukaani-project/xz/pull/75 (the first commit)
According to the numbers there, this may improve encoding
speed by about 3-5 %.

This enables the 8-byte method on MSVC ARM64 too which
should work but wasn't tested.
