[DAGCombiner] add (sext i1 X), 1 --> zext (not i1 X)

Besides better codegen, the motivation is to be able to canonicalize this pattern 
in IR (currently we don't) knowing that the backend is prepared for that.

This may also allow removing code for special constant cases in 
DAGCombiner::foldSelectOfConstants() that was added in D30180.

I'm proposing a fold for increment-of-sexted-bool in:

...so we need to know what happens in more cases like these.
