[Bug fortran/29892] substring out of bounds: Missing variable name for variables with parameter attribute

[fxcoudert at gcc dot gnu dot org]

Fixed for array bounds checking on mainline. I'll backport the patch to 4.2 in
some time.

We still need to figure something out for the substrings case (see comment #0):

>         expr->where.lb->linenum); ):

> => Unsolvable as no name exists

>       print *, s2(9:16)
> The problem is that s and s2 have the parameter type
