As reported by Joerg Sonnenberger in IRC, for 32-bit systems, where pointer and size_t are 32-bit, if you use 64-bit-wide variable in the loop, you could end up with loop exit count being of the type wider than the size_t. Now, i'm not sure if we can produce `bcmp` from that (just truncate?), but we certainly should not assert/miscompile. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@374811 91177308-0d34-0410-b5e6-96231b3b80d8
