Major patch to fix reporting of unused imports
This patch, joint work between and Ian and Simon, fixes Trac #1074 by reporting unused import declarations much more accuratly than before. The specification is described at http://hackage.haskell.org/trac/ghc/wiki/Commentary/Compiler/UnusedImports The implementation is both easier to understand than before, and shorter too. Also fixed are #1148, #2267 Also fixed is -ddump-minimal imports, which now works properly, fixing Trac #1792.
