[Patch, Fortran] PR 58355: [4.7/4.8/4.9 Regression] [F03] ICE with TYPE, EXTENDS before parent TYPE defined

[Janus Weil]

Hi all,

the straightforward patch in the attachment does two things:

1) It prevents a segfault, which is a regression on 4.7/4.8/trunk (by
simply switching the order of two statements).
2) It modifies an error message, which was not perfectly correct in my opinion.

The patch was regtested successfully on x86_64-unknown-linux-gnu. Ok for trunk?

Part #1, as a regression fix, should also be backported to 4.7 and 4.8. Ok?

Cheers,
Janus
