Fix the dynflags consistency code It was checking to see whether the hscTarget is HscC or HscLlvm, and changing it to HscC otherwise. But this meant that as well as rejecting HscAsm, it also rejected HscInterpreted and HscNothing. Now we just check whether it's HscAsm.

Fix type variable scoping in nested pattern type signatures (#7827)
11:01 AM Changeset in ghc [2eaf46fb]late-dmd by Nicolas Frisby <nicolas.frisby@…>
O2 now runs another demand analysis before CorePrep (fixes #7782) Its specific flag is -flate-dmd-anal The bulk of this patch merely simplifies the treatment of wrappers in inteface files. In particular, the body of a wrapper is now encoded (just like any other InlineStable) instead regenerating the wrapper from its strictness signature and worker id. Consequences: 0) simplifies a special case; there's plenty of knock-on code elimination from no longer having ids in UnfoldingSource 1) increases the size of .hi (some significantly, esp GHC.Classes) 2) increases compile time a bit (eg ~ +1% over nofib) 3) accomodates the late demand analysis: the previous treatment of wrappers in interface files caused CoreLint errors when combined with the second demand analysis

ignore RealWorld in size_expr; flag to keep w/w from creating sharing size_expr now ignores RealWorld lambdas, arguments, and applications. Worker-wrapper previously removed all lambdas from a function, if they were all unused. Removing *all* value lambdas is no longer allowed. Instead (\_ -> E) will become (\_void -> E), where it used to become E. The previous behavior can be recovered via the new -ffun-to-thunk flag.
