Mesa 17.3 branched off master on 2017-10-23.
LLVM 6 branched off trunk on 2018-01-03.
In the ~2.5 months between, there could have been any number of
backwards incompatible changes in LLVM trunk, which aren't accounted for
in Mesa 17.3.

I think it's safer to make it clear that Mesa 17.3 doesn't and can't
support LLVM 6.
