[patch, fortran] PR33152 Initialization/declaration problems in block data

[Jerry DeLisle]

:ADDPATCH fortran]

The attached patch resolves the issues (several variations) identified in the PR.

The patch removes wrong error messages and adds a new one.  Fairly self explanatory.

New test case provided.

Regression tested on x86-64-unknown-linux-gnu.

OK for trunk?
