[PATCH] Mingw-w64 driver for clang

[Yaron Keren]

Thanks. 

The llvm SEH patch 

 https://github.com/Alexpux/MINGW-packages/blob/master/mingw-w64-clang/llvm-win64-exceptions.patch

is already in the current code,  so only the clang patch you linked is required.

We have an old revision for the clang patch here

 http://reviews.llvm.org/D3419

the code may need minor fixes to current patch / current trunk. If you have the time to push it through.
