9fc347aa4e [DAG] PromoteIntRes_BUILD_VECTOR - extend constant boolean vectors according to target BooleanContents 
PromoteIntRes_BUILD_VECTOR currently always ANY_EXTENDs build vector operands, but if this is a constant boolean vector we're losing the useful ability to keep the vector matching the BooleanContents mode used by the target.

This patch extends constant boolean vectors according to target BooleanContents, allowing a number of additional all-bits folds (notable XOR -> NOT conversions) to occur.

47b7d13459 [PowerPC] Emit XXSEL for vec_sel and code that has the same pattern 
As pointed out in https://bugs.llvm.org/show_bug.cgi?id=41777
we do not emit a vector select even when the pretty much asks for one.
This patch changes that.
