Track #included files for recompilation checking (#4900, #3589)
This was pretty straightforward: collect the filenames in the lexer,
and add them in to the tcg_dependent_files list that the typechecker
collects.
Note that we still don't get #included files in the ghc -M output.
Since we don't normally lex the whole file in ghc -M, this same
mechanism can't be used directly.
