libstdc++: Fix some -Wpedantic warnings in regex tests

Browse Source 
These tests can be run as C++11, so should use a string literal with the
static assertions.

libstdc++-v3/ChangeLog:

	* testsuite/28_regex/algorithms/regex_match/multiline.cc: Add
	string to static_assert.
	* testsuite/28_regex/sub_match/lwg3204.cc: Likewise.
