handle equality memcmp of 8 bytes on x86-64 with two unaligned loads and a compare. On other targets we end up with a call to memcmp because we don't want 16 individual byte loads. We should be able to use movups as well, but we're failing to select the generated icmp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92107 91177308-0d34-0410-b5e6-96231b3b80d8
