[Patch, Fortran, 4.5 Regression] PR 40848

[Janus Weil]

Hi all,

here is a fix for a regression, which was introduced by r148519. With
this revision I implemented better error messages for interface
checks, with the side effect that I changed the order of some checks
in gfc_compare_interfaces. The ICE here comes about because
'count_types_test' is called only after 'generic_correspondence', and
the patch reverts this to its original order. It also makes sure
'count_types_test' is only called for generic interfaces (since
14.1.2.3 in the F95 standard only applies to generic interfaces).

The testsuite yields no failures with this patch on
x86_64-unknown-linux-gnu. Ok for trunk?

Cheers,
Janus
