SEH codegen/driver patch

For x64, Kai Nacke, aka redstar, has been working on SEH in LLVM.

With his WIP patch (see e.g. http://lists.cs.uiuc.edu/pipermail/llvm-
commits/Week-of-Mon-20140106/200863.html), and my MinGW Driver code (see
http://llvm.org/bugs/show_bug.cgi?id=18546), and attached modifications for the
CG/Driver/Frontend, the necessary changes are done to generate calls to the seh
gcc personality functions. Basic testing (hello world throw-catch) works with
GCC 4.8.2's libraries.

Scratch that. 64-bit eh does not work with this patch. seh stuff is emitted though.
