Update to work with pkhuong's latest sse support branch.

Mostly changing register class and primitive type names for VOP
arguments and return values. Also allocating the pre-defined
constants with the right type-specific tags.

Partial constant folding transforms for boolean operations almost
certainly don't match anything due to lack of EQL support.
Merge branch 'feature/sse3and4.1' of github.com:TOYOZUMIKouichi/cl-simd into feature/sse3and4.1
