Mateusz Guzik a8e3f99ec1 amd64: implement memcmp in assembly 
Both the in-kernel C variant and libc asm variant have very poor performance.
The former compiles to a single byte comparison loop, which breaks down even
for small sizes. The latter uses rep cmpsq/b which turn out to have very poor
throughput and are slower than a hand-coded 32-byte comparison loop.

Depending on size this is about 3-4 times faster than the current routines.
