gentoo-overlay/sys-devel/llvm/files/llvm-3.3-R600_debug.patch

Fixes compilation of llvm-3.3 on gcc-4.6 and 4.7 when VIDEO_CARDS=radeon

This issue is caused because although Q is a multiset the original code tries to get
a set iterator which can't be converted in a multiset one.

The fix is as simple as just using a multiset iterator.
