c++: Constant expression parsing and parameters.
The difference between a "potential" constant-expression and a regular
constant-expression is the treatment of parameters; in a constexpr function,
a parameter is potentially constant when evaluating a call to that function,
but it is not constant during parsing of the function.
cp_parser_constant_expression should check the latter rather than the
former.
gcc/cp/ChangeLog:
* cp-tree.h (is_rvalue_constant_expression): Declare.
* constexpr.c (is_rvalue_constant_expression): New.
* parser.c (cp_parser_constant_expression): Use it.
* decl.c (cp_finish_decl): Try to treat a constexpr initializer in a
template as constant.
