Rewrite Layer YUY2 MMX
Template Layer YUY2 C functions
Add SSE2 versions of Layer YUY2 functions
Rewrite Layer RGB32 MMX
Add SSE2 versions of Layer RGB32 functions
Enable layer in x64 mode
Remove some leftovers and alignment check on most RGB32 Layer routines
Rewrite tweak ISSE asm to intrinsics.

It's pretty much useless, just for completeness.
Rewrite Compare ISSE code
Add Compare SSE2 routine
