Don't defer type errors when evaluating a GHCi expression It is unhelpful here because the expression will get evaluated right away anyway, thus emitting a redundant warning followed by an equivalent runtime exception. If the expression were an ill-typed pure expression, _three_ equivalent type errors would get emitted (due to the two-phase typechecking done in 'Plan C')

Tweak the HADDOCK_DOCS regex in validate It's less precise now, but still good enough for what we need, and this way we don't need to have literal tabs in the file.

Give a unfolding argument discount proportional to the number of available arguments Ensures that h1 gets inlined into its use sites in cases like: """ h1 k = k undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined a = h1 (\x _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ -> x) b = h1 (\_ x _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ -> x) """ I've benchmarked this on nofib (albeit recompiling only the benchmarks, not the library) and it hardly shifts the numbers - binary size is up by 0.1% at most (average 0.0%) and the worst-case allocation increase is 0.2% (best case -0.1%, 0.0% average). If you also rebuild the libraries with this change, the only further change is a +0.2% allocation increase in cacheprof. So this looks like a pretty low-risk change that will considerably benefit certain programs.

Improve the case-alternative heap checks The code we were generating for heap-checks in algebraic case alternatives wasn't working well with the common-block eliminator. A small tweak to make the heap-check failure jump back to the same place in all branches lets the common-block eliminator squash more code.

Improve common-block elimination We need to compare middle nodes and expressions modulo the BlockId mapping too, because there are references to BlockIds in CmmStackSlot and CmmBlock. This lets us catch more common blocks - in particular we can share the heap-check fail code between multiple case alternatives, which is most cool.
