warning to an error. C++ bans it, and both GCC and EDG diagnose it as
an error. Microsoft allows it, so we still warn in Microsoft
mode. Fixes <rdar://problem/11135644>.

- Find a legal vector type before casting and extracting element from it.
- As the new vector type may have more than 2 elements, build the final
  hi/lo pair by BFS pairing them from bottom to top.

Add a PatFrag to match X86tcret using 6 fixed registers or less. This

The current implementation does not allow more than 32 types to be properly handled with target lowering. This doubles the size to 64bit types and easily allows extension to more types.
