[SimplifyCFG] Don't try to create metadata-valued PHIs

We can't create metadata-valued PHIs; don't try to do so when sinking.

I created a test case for this using the @llvm.type.test intrinsic, because it
takes a metadata parameter and does not have severe side effects (thus
SimplifyCFG is willing to otherwise sink it).

Previously, running the test case would crash with:

  Invalid use of metadata!
    %.sink = select i1 %flag, metadata <...>, metadata <0x4e45dc0>
  LLVM ERROR: Broken function found, compilation aborted!
