[PATCH] CodeGen support for x86_64 SEH catch handlers in LLVM

[Reid Kleckner]

This patch is stripped down to just two things now:

- Splitting the single landing pad BB into 1 per selector
- Emitting the EH table expected by __C_specific_handler

This seems pretty mechanical and not very interesting from a design perspective. Looks good?
