target/i386: Rewrite simple integer vector helpers
Rewrite the "simple" vector integer helpers in preperation for AVX support.
While the current code is able to use the same prototype for unary
(a = F(b)) and binary (a = F(b, c)) operations, future changes will cause
them to diverge.
No functional changes to existing helpers
