[Patch, fortran] PR42783 - [4.5 Regression] Bogus Array bounds violation with optional array argument

[Paul Richard Thomas]

Dear Tobias,

Whilst being ill messed up my involvement in the gfortran meeting on
Sunday, a day in bed yesterday did wonders for regression fixing :-)

OK, I'll commit the fix for PRs42783 and 42742 tonight and will await
a green light on PR42736.

I do not intend to write a testcase for PR42742 because the fix is so
trivial. Were it to regress, it would do so for reasons that have
nothing to do with this PR.

Thanks for the review

Paul
