Subject: [PATCH] LWG 3050 Fix cv-qualification of convertibility constraints

This issue hasn't been voted into the working draft yet, but it's been
approved by LWG and is obviously correct.

	* include/std/chrono (duration, operator*, operator/, operator%): Use
	const-qualified type as source type in is_convertible constraints.
	* testsuite/20_util/duration/arithmetic/dr3050.cc: New.
	* testsuite/20_util/duration/cons/dr3050.cc: New.
	* testsuite/20_util/duration/literals/range.cc: Rename to...
	* testsuite/20_util/duration/literals/range_neg.cc: Here. Adjust
	dg-error lineno.

Tested powerpc64le-linux, committed to trunk.
