[Patch, Fortran] PR 56081: [4.7/4.8 Regression] Seg fault ICE on select with bad case

Hi all,

here is a regression fix for an ICE-on-invalid bug with SELECT CASE.
The check to reject non-scalar selectors had been present in 4.6, but
was apparently removed when CLASS arrays were implemented.

The patch re-inserts the check and makes sure it is not applied to
SELECT TYPE (where class arrays are allowed).

Regtested on x86_64-unknown-linux-gnu. Ok for trunk and 4.7?

Cheers,
Janus
