[PATCH] Fix WinEHPrepare bug with multiple catch handlers

[Reid Kleckner]

LGTM with the `#if 0` code removed. The promotion seems like a nice simplification. :)

----------------
My understanding is that you are also required to change the INITIALIZE_TM_PASS code to use INITIALIZE_TM_PASS_BEGIN / END and INITIALIZE_PASS_DEPENDENCY(DominatorTreeWrapperPass). See DwarfEHPrepare. I could be wrong, the pass registry stuff is all ugly goo that will hopefully be removed when the new pass manager happens.
