[PATCH] Outline functions for SEH with the MSVC environment

[Reid Kleckner]

Neat, so these tests pass? Seems like this approach is working! =D

The MSVCEHPrepare.cpp file has a bunch of Allman style braces, which should be fixed.

I feel like this is probably a good chunk of logic to commit, but we're a bit blocked on review. Long term, will need to do analysis to share regions of cleanup code in separate outlined functions rather than duplicating code.

This comment seems like it got mis-edited. :) Maybe "..., we want to stop everything. The cloning director is reponsible for inserting a terminator here."
