We can't enable the verifier for tests with SI_IF and SI_ELSE, because these instructions are always followed by a COPY which copies their result to the next basic block. This violates the machine verifier's rule that non-terminators can not folow terminators. Reviewed-by: Vincent Lejeune<vljn at ovi.com> llvm-svn: 192366
