4a2b684ef4 modify SAVE_XMM for potential 64bit use
the win64 abi requires saving and restoring xmm6:xmm15. currently
SAVE_XMM and RESTORE XMM only allow for saving xmm6:xmm7. allow
specifying the highest register used and if the stack is unaligned.

XMM6/7 are used in these functions, and need to be saved.

b523dd51bd add missing GET_GOT/RESTORE_GOT pairs
These functions made global references but did not set up the GOT,
causing compilation failures in PIC mode.

4db2076594 Add SSE2 subtract functions
Instead of doing 8-bit data unpack and 16-bit subtraction, use
psubb to do 16 8-bit subtractions and pcmpgtb to preserve the
sign information. This does not bring noticable gain since
these functions are not called frequently.
