Add debugPprType
We pretty-print a type by converting it to an IfaceType and
pretty-printing that. But
(a) that's a bit indirect, and
(b) delibrately loses information about (e.g.) the kind
on the /occurrences/ of a type variable
So this patch implements debugPprType, which pretty prints
the type directly, with no fancy formatting. It's just used
for debugging.
I took the opportunity to refactor the debug-pretty-printing
machinery a little. In particular, define these functions
and use them:
ifPprDeubug :: SDoc -> SDOc -> SDoc
-- Says what to do with and without -dppr-debug
whenPprDebug :: SDoc -> SDoc
-- Says what to do with -dppr-debug; without is empty
getPprDebug :: (Bool -> SDoc) -> SDoc
getPprDebug used to be called sdocPprDebugWith
whenPprDebug used to be called ifPprDebug
So a lot of files get touched in a very mechanical way
