This test was using the inliner and other optimizations to test a case that's actually a bug anyway. Bug and possible fix/discussion described here ( http://reviews.llvm.org/D3714 ). But the functionality that was implemented along with this test is still desired, so simplify the test to verify a more obvious/less wrong case that the functionality addressed: looking through const sugar to the underlying type when emitting a constant (so the constant is emitted as signed/unsigned as appropriate depending on the signedness of the underlying type). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208504 91177308-0d34-0410-b5e6-96231b3b80d8
