[cfe-dev] Win64 exception handling

[hoganmeier at gmail.com]

Some time ago the patch for Win64 exception handling was finally merged.
There are still serious bugs though and Twobit attached a preliminary  
patch to that review.
http://reviews.llvm.org/D4081#52

But nothing happened since then.

I tried to fix it according to rnk's comment "the individual .pdata  
sections should be comdat associative with the individual .text sections"  
but don't know enough about the respective llvm internals.

Could anybody finalize that patch and get this in?
