Noah Goldstein 9469261cf1 x86: Only align destination to 1x VEC_SIZE in memset 4x loop 
Current code aligns to 2x VEC_SIZE. Aligning to 2x has no affect on
performance other than potentially resulting in an additional
iteration of the loop.
1x maintains aligned stores (the only reason to align in this case)
and doesn't incur any unnecessary loop iterations.
