Jonathan Wakely cdd2d448d8 libstdc++: Fix constraints on std::optional comparisons [PR 96269]
The relational operators for std::optional were using the wrong types
in the declval expressions used to constrain them. Instead of using
const lvalues they were using non-const rvalues, which meant that a type
might satisfy the constraints but then give an error when the function
body was instantiated.

libstdc++-v3/ChangeLog:

	PR libstdc++/96269
	* include/std/optional (operator==, operator!=, operator<)
	(operator>, operator<=, operator>=): Fix types used in
	SFINAE constraints.
	* testsuite/20_util/optional/relops/96269.cc: New test.
