no assert at all. ;] Some of these should probably be switched to llvm_unreachable, but I didn't want to perturb the behavior in this patch. Found by -Wstring-conversion, which I'll try to turn on in CMake builds at least as it is finding useful things. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205091 91177308-0d34-0410-b5e6-96231b3b80d8
