System.Info now exports:

  compilerName :: String
  compilerVersion :: Data.Version.Version

as requested ages ago by Template Haskell users.  This allows
"conditional compilation" based on the GHC version in TH code.

I've implemented compilerName for all compilers (I hope).  Other
compiler vendors are encouraged to provide their own implementations
of compilerVersion.
