bd6006e427804a6c1ada75d8b6bc8ad129a1c862 add small_memcpy()
That last CL that started using non-constant-sized memcpy() must have
thrown off the optimizer... the stores do bizarre things like,
store 16 byte vector to stack
load low 8 bytes back from stack to register A
load high 8 bytes back from stack to register B
store to dst+0 from register A
store to dst+8 from register B
when they could do
store 16 byte vector to dst+0
This small_memcpy() that uses __builtin_memcpy()
when possible restores the sanity.
