* Parse OPTIONS properly and cache the result.
Use the lexer to parse OPTIONS, LANGUAGE and INCLUDE pragmas.
This gives us greater flexibility and far better error
messages. However, I had to make a few quirks:
* The token parser is written manually since Happy doesn't
like lexer errors (we need to extract options before the
buffer is passed through 'cpp'). Still better than
manually parsing a String, though.
* The StringBuffer API has been extended so files can be
read in blocks.
I also made a new field in ModSummary called ms_hspp_opts
which stores the updated DynFlags. Oh, and I took the liberty
of moving 'getImports' into HeaderInfo together with
'getOptions'.
