Regressed with r11-4501
c++: Prevent warnings for value-dependent exprs [PR96742]
Here, in r11-155, I changed the call to uses_template_parms to
type_dependent_expression_p_push to avoid a crash in C++98 in
value_dependent_expression_p on a non-constant expression. But that
prompted a host of complaints that we now warn for value-dependent
expressions in templates. Those warnings are technically valid, but
people still don't want them because they're awkward to avoid. This
patch uses value_dependent_expression_p or type_dependent_expression_p.
But make sure that we don't ICE in value_dependent_expression_p by
checking potential_constant_expression first.
