[Patch, Fortran, OOP] PR 54594: Type-bound ASSIGNMENTs (elemental + array version) rejected as ambiguous

[Janus Weil]

Hi all,

here is an OOP patch for type-bound generics. The problem was that
specifics with polymorphic arguments of different ranks were wrongly
rejected as ambiguous, because 'gfc_compare_types' did not properly
handle CLASS arrays. The patch fixes this is regtests cleanly on
x86_64-unknown-linux-gnu. Ok for trunk?

Cheers,
Janus
