i386: Improve and optimize ix86_expand_sse_movcc
Modernize ix86_expand_sse_movcc to use expand_simple_{unop,binop}
infrastructure to avoid manual twiddling with output registers.
Also fix a couple of inconsistent vector_all_ones_operand usages,
break a couple of unnecessary else-if chains, eliminate common
subexpressions and do some general code simplifications.

gcc/ChangeLog:
* config/i386/i386-expand.c (ix86_expand_sse_movcc): Use
expand_simple_unop and expand_simple_binop instead of manually
constructing NOT, AND and IOR RTXes. Use vector_all_ones_operand
consistently. Eliminate common subexpressions and simplify code.
* config/i386/sse.md (<any_logic:code><MODEF:mode>3): New expander.
(<any_logic:code><MODEF:mode>3): Make public.
