Jakob Stoklund Olesen 7d33c5739f Don't add CFG edges for redundant conditional branches. 
IR that hasn't been through SimplifyCFG can look like this:

  br i1 %b, label %r, label %r

Make sure we don't create duplicate Machine CFG edges in this case.

Fix the machine code verifier to accept conditional branches with a
single CFG edge.
