Updates LLVM and Clang to pre-3.6, which adds additional features used in CMSSW. In addition to that resolves some asserts in Clang while compiling CMSSW. Same PR (#1220) was merged into DEVEL IBs ~2 months ago. Plain CMSSW now fully compiles and links with Clang.

We will probably again update Clang soonish as 3.6 RC1 is now released, but not tested with CMSSW.

Also resolves some Clang asserts in CMSSW.
