[patch, fortran] PR 29393: Ranks of PARAMETER-lhs in initializations

[Erik Edelmann <erik dot edelmann at iki dot fi>]

This patch fixes PR 29393.  Problem: In expr.c
(simplify_parameter_variable), we replace the original expression p with
a simplified experssion derived from p->symtree->n.sym->value.  Now, if
p->symtree->n.sym->value has different rank than p, the rank will become
wrong.  This oneliner will restore the rank to the correct value.

Tested on trunk, Linux/x86.  I intend to commit it tomorrow as obvious to trunk
and, if it passes regressiontesting, 4.2 and 4.1, unless there are
objections.
