Check the llvm version against a fixed list.

This change is thanks to Peter Hull, who independently resolved
the 2.8 vs 2.8svn issue this way. His patch checked the version
string against a fixed set of options, which is easier to read
and simpler to adjust in the future.
(cherry picked from commit 83cc297561a78ad13fcd1c2943f17ace81c725b8)
