Revert "Revert r212640, "Add trunc (select c, a, b) -> select c (trunc a), (trunc b) combine.""
Don't try to convert the select condition type.

Revert r212640, "Add trunc (select c, a, b) -> select c (trunc a), (trunc b) combine."
This caused miscompilation on, at least, x86-64. SExt(i1 cond) confused other optimizations.

Add trunc (select c, a, b) -> select c (trunc a), (trunc b) combine.
Do this if the truncate is free and the select is legal.

using shifts, with ISD::EXTRACT_VECTOR_ELT, which is a no-op.
