      ghc-heap: Introduce closureSize · cb61371e
      Ben Gamari authored
      This function allows the user to compute the (non-transitive) size of a
      heap object in words. The "closure" in the name is admittedly confusing
      but we are stuck with this nomenclature at this point.

      compiler: Disable atomic renaming on Windows · 1c1b63d6
      Ben Gamari authored
      As discussed in #16450, this feature regresses CI on Windows, causing
      non-deterministic failures due to missing files.

      Add location to the extra-constraints wildcard · 600a1ac3
      Simon Peyton Jones authored
      The extra-constraints wildcard had lost its location
      (issue #16431).
      
      Happily this is easy to fix.  Lots of error improvements.

      Improve error recovery in the typechecker · 4927117c
      Simon Peyton Jones authored
      Issue #16418 showed that we were carrying on too eagerly after a bogus
      type signature was identified (a bad telescope in fact), leading to a
      subsequent crash.
      
      This led me in to a maze of twisty little passages in the typechecker's
      error recovery, and I ended up doing some refactoring in TcRnMonad.
      Some specfifics
      
      * TcRnMonad.try_m is now called attemptM.
      
      * I switched the order of the result pair in tryTc,
        to make it consistent with other similar functions.
      
      * The actual exception used in the Tc monad is irrelevant so,
        to avoid polluting type signatures, I made tcTryM, a simple
        wrapper around tryM, and used it.
      
      The more important changes are in
      
      * TcSimplify.captureTopConstraints, where we should have been calling
        simplifyTop rather than reportUnsolved, so that levity defaulting
        takes place properly.
      
      * TcUnify.emitResidualTvConstraint, where we need to set the correct
        status for a new implication constraint.  (Previously we ended up
        with an Insoluble constraint wrapped in an Unsolved implication,
        which meant that insolubleWC gave the wrong answer.
