[patch, fortran] Fix PR 72714, ICE on invalid

[Thomas Koenig]

Hello world,

the attached patch fixes a 7/8/9 regression by rejecting an invalid
expression in coarray allocation that led to an ICE.  It also adds a few
more checks.

One point that is checked for is that, unlike normal arrays, coarrays
cannot be empty.

Regression-tested. OK for trunk and affected branches?

Regards

	Thomas
