bb2dd7619f libstdc++: Remove dg-options "-std=gnu++20" from 26_numerics tests 
The testsuite will automatically select C++20 for these tests now, and
removing the hardcoded -std option allows them to be tested for C++23
and C++26 as well.

libstdc++-v3/ChangeLog:

	* testsuite/26_numerics/accumulate/constexpr.cc: Remove
	dg-options -std=gnu++2a.

0532452dcd libstdc++: Replace incorrect static assertion in std::reduce [PR95833] 
The standard does not require the iterator's value type to be
convertible to the result type, it only requires that the result of
dereferencing the iterator can be passed to the binary function.

libstdc++-v3/ChangeLog:

	PR libstdc++/95833
	* include/std/numeric (reduce(Iter, Iter, T, BinaryOp)): Replace
	incorrect static_assert with ones matching the 'Mandates'
	conditions in the standard.
	* testsuite/26_numerics/reduce/95833.cc: New test.

d7b2d92747 libstdc++: Remove redundant -std=gnu++17 option from algorithm tests 
GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
dg-options directive prevents running these tests with different modes
such as -std=c++17 or -std=gnu++20.
