* More refactoring in RnNames
I rather self-indulgently spent a chunk of yesterday working on
refactoring RnNames further. The result is significantly simpler:
* A GlobalRdrElt gets an extra field, gre_par, which records
the parent (if any) of the name
* ImportAvails has two fields deleted: imp_env and imp_parent.
The information provided by these fields was only used when
processing the export list; and the same information is now readily
generated from the GlobalRdrElts in the GlobalRdrEnv
I also did some tidying up; notably moving AvailEnv stuff from
TcRnTypes to RnNames.
The result is tha the compiler is some 130 lines shorter than before
M ./compiler/basicTypes/RdrName.lhs -13 +32
M ./compiler/main/HscTypes.lhs -5 +2
M ./compiler/rename/RnEnv.lhs -21 +25
M ./compiler/rename/RnExpr.lhs -1 +1
M ./compiler/rename/RnHsDoc.hs -2 +2
M ./compiler/rename/RnNames.lhs -292 +252
M ./compiler/typecheck/TcRnDriver.lhs -14 +6
M ./compiler/typecheck/TcRnMonad.lhs -8 +1
M ./compiler/typecheck/TcRnTypes.lhs -111 +9
