#3287: Malformed LANGUAGE pragma causes GHC panic

Hi, I tried to compile file starting with {-# LANGUAGE
-XExistentialQuantification #-}
which is of course wrong, but GHC should handle this more gracefully than
ghc: panic! (the 'impossible' happened)
(GHC version 6.10.2 for i386-unknown-linux):
getOptions'.parseLanguage(2) went past eof token
The 6.8.2 version surprisingly works better:
test.hs:1:0: cannot parse LANGUAGE pragma
