Fix pasto in the substitute_and_fold_engine merge with evrp.

The original code only propagated into PHI arguments if the value was
a constant.  This behavior was lost in the conversion, allowing
any value (SSAs for instance) to be propagated into PHIs.

gcc/ChangeLog:

PR tree-optimization/95649
* tree-ssa-propagate.c (propagate_into_phi_args): Do not propagate unless
value is a constant.

gcc/testsuite/ChangeLog:

* g++.dg/tree-ssa/pr95649.C: New test.
* gcc.dg/tree-ssa/pr95649.c: New test.
