[v3] is_modulo

Subject: [v3] is_modulo

Hello,

the attached follows the precisions on the definition of is_modulo in DR 612. I believe this is what the values always should have been, so I didn't make the change conditional to C++11.

PR 22200 can remain open if people want to discuss the interaction with -fwrapv, but false is the safe value.

I ran the testsuite, to make sure there wasn't a huge typo that would prevent the file from compiling, and the only failure was the usual 22_locale/time_get/get_date/wchar_t/4.cc.

	PR libstdc++/22200
	* include/std/limits (numeric_limits<>::is_modulo): false for
	signed types.
