PR 52631 is a missed-optimization regression where we fail to lookup a
simplified expression when value numbering the ssa graph to see if the
simplified expression already has a value number.
Andrew Pinski had a patch that was 99% complete in the PR; Richard
Biener suggested a relatively min

gfortran.dg/inquire_10.f90 has failed for newlib targets while
linking, because (besides cygwin and some linux support), newlib
doesn't have getcwd:

You generally don't have to ask for approval for changes like this.
