improve optimization of invoke instructions: - simplifycfg: invoke undef/null -> unreachable - instcombine: invoke new -> invoke expect(0, 0) (an arbitrary NOOP intrinsic; only done if the allocated memory is unused, of course) - verifier: allow invoke of intrinsics (to make the previous step work) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159146 91177308-0d34-0410-b5e6-96231b3b80d8
