(Specifically, don't insert an arbitrary instruction before a PHI.)

Use it to preserve metadata attached to a branch when re-writing it in InstCombine. Add metadata to the canonicalize_branch InstCombine test, and check that it is tranformed correctly.

This was caught by llvm-gcc self host, not because there's anything special about llvm-gcc, but because it is the only test for nondeterminism we currently have. Unit tests don't work well for everything; we should always try to have a nondeterminism stress test running.
