Add -mcpu to memcpy / memset tests to ensure they behave the same on all hosts / targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100101 91177308-0d34-0410-b5e6-96231b3b80d8

Fix sdisel memcpy, memset, memmove lowering: 1. Makes it possible to lower with floating point loads and stores. 2. Avoid unaligned loads / stores unless it's fast. 3. Fix some memcpy lowering logic bug related to when to optimize a load from constant string into a constant. 4. Adjust x86 memcpy lowering threshold to make it more sane. 5. Fix x86 target hook so it uses vector and floating point memory ops more effectively. rdar://7774704 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100090 91177308-0d34-0410-b5e6-96231b3b80d8
