* Fix sdisel memcpy, memset, memmove lowering:Evan Cheng2010-04-012-108/+156
| | | | | | | | | | | | | | 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

The unwinder will see the %sel call as a clean-up and, if it doesn't have a catch further up the call stack, it will skip running it. But there *is* another catch up the stack -- the catch for the %lpad. However, we can't see that. This is fixed in code-gen, where we detect this situation, and convert the "clean-up" selector call into a "catch-all" selector call.
