8	cache ghc-version-specific info	claus	claus	"There is really no reason for every editing session to ask ghc about the languages and options it supports. Cache this info and look it up by version. Only call out to ghc again if the cache is missing or doesn't cover the current ghc version.

Only issue: another file to find a writeable location for, on all platforms..

Oh, now that we use `autoload`, there should also be no need for both `ghc.vim` and `haskell_doc.vim` to query the ghc version (and one of the version-comparison functions could also go!).

All these extraneous calls to ghc noticably slow down startup."	defect	closed	major		---		fixed
