No functions are changed. It just renames generic implementations from
'{func}_sse2' to '{func}_generic'. This is just because the postfix
"_sse2" was overloaded and was used for files that had hand-optimized
sse2 assembly implementations and files that just redirected back
to the generic implementation.

Full xcheck passed on x86_64.
---
Note this change is in preperation to further changes to the file
organization in the multiarch directory.
