Fix vectorization regressions on the SPARC
This fixes the vectorization regressions present on the SPARC by switching
from vcond[u] patterns to vec_cmp[u] + vcond_mask_ patterns. While I was
at it, I merged the patterns for V4HI/V2SI and V8QI enabled with VIS 3/VIS 4
to follow the model of those enabled with VIS 4B, and standardized all the
mnemonics to the version documented in the Oracle SPARC architecture 2015.
