[PATCH] [X86] Look for scalar through one bitcast when lowering to VBROADCAST.

[Ahmed Bougacha]

Note that the test file isn't in tree right now: I added it locally, and submitted a patch against it (to make it easier to review).

So I can totally merge it with the vector-shuffle-* if you prefer (seems like you do, I'm neutral; let's do that!).
