So, rev #5446 was verified to work in another thread[0] but I checked out
LLVM's svn repository (via the git mirror) and built the

$ llvm-config --version
3.3svn

which seems to not call some class "llvm:Attributes" (as in the 3.2svn or
so) but "llvm:Attribute" (as it was before), again.

The attached patch makes compilation work again for the more recent SVN
version. These LLVM people seem to be really uncertain about naming :-)

FYI, the commit logs show that:

a) Somewhen after rev #164727 (September) the llvm:Attribute class must have
   vanished.
b) The re-renaming to llvm:Attribute was at rev #170502 (today morning!).

c) IRBuilder.h changed location with rev #159421 (June).

Regards,
Tobi
