Pmc: Better SCC annotations and trace outputwip/improve-pmc
While investigating #20106, I made a few refactorings to the pattern-match
checker that I don't want to lose. Here are the changes:
* Some key functions of the checker now have SCC annotations
* Better `-ddump-ec-trace` diagnostics for easier debugging. I added
'traceWhenFailPm' to see *why* a particular `MaybeT` computation fails and
made use of it in `instCon`.
I also increased the acceptance threshold of T11545, which seems to fail
randomly lately due to ghc/max flukes.
