9380d5daff Kill and collapse outstanding DomainValues.
DomainValues that are only used by "don't care" instructions are now
collapsed to the first possible execution domain after all basic blocks
have been processed.  This typically means the PS domain on x86.

For example, the vsel_i64 and vsel_double functions in sse2-blend.ll are
completely collapsed to the PS domain instead of containing a mix of
execution domains created by isel.

2fc9d5171e Implement initial memory alignment awareness for SSE instructions. Vector loads
and stores that have a specified alignment of less than 16 bytes now use
instructions that support misaligned memory references.
