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
