Update jump threading so that whenever possible it re-uses the original
block, rather than bypassing it. This lays the groundwork for a subsequent
change that will allow jump threading when the block with the threadable
jump has side effects.

Also handle the case where we have both a fall through pred and an ambiguous
pred, by treating the fall through pred as ambiguous.

Notes on diffs: a few cases where we do more jump threading (since we now "handle" the amb+ft case), and a few others where we stop doing a CSE as we clean up block more often and so delete a redundant expression occurrence.

Is there a before/after flow graph picture that would help explain the change?

src/coreclr/jit/redundantbranchopts.cpp Outdated
// a new block to allow changing that fall through to a jump, so if we have
// both a pred that is not a true pred, and a fall through, we defer optimizing
// the fall through pred as well.
// * We note if there is an un-ambiguous that pred falls through to block.

"We note if there is an un-ambiguous that pred" => missing word after "ambiguous"?

src/coreclr/jit/redundantbranchopts.cpp Outdated
// per (4) below.
//
// (4) If we don't have an ambiguous pred, and we have a fall through, we leave
// all preds in the fall through set alone -- they contiuue branching to block.

@BruceForstall is the newly added flow picture enough or do you think it needs something more elaborate?
