libstdc++: Fix tests for std::vector range operations

The commit I pushed was not the one I'd tested, so it had older versions
of the tests, with bugs that I'd already fixed locally. This commit has
the fixed tests that I'd intended to push in the first place.

libstdc++-v3/ChangeLog:

	* testsuite/23_containers/vector/bool/cons/from_range.cc: Use
	dg-do run instead of compile.
	(test_ranges): Use do_test instead of do_test_a for rvalue
	range.
	(test_constexpr): Call function template instead of just
	instantiating it.
	* testsuite/23_containers/vector/bool/modifiers/assign/assign_range.cc:
	Use dg-do run instead of compile.
	(do_test): Use same test logic for vector<bool> as for primary
	template.
	(test_constexpr): Call function template instead of just
	instantiating it.
	* testsuite/23_containers/vector/bool/modifiers/insert/append_range.cc:
	Use dg-do run instead of compile.
	(test_ranges): Use do_test instead of do_test_a for rvalue
	range.
	(test_constexpr): Call function template instead of just
	instantiating it.
	* testsuite/23_containers/vector/bool/modifiers/insert/insert_range.cc:
	Use dg-do run instead of compile.
	(do_test): Fix incorrect function arguments to match intended
	results.
	(test_ranges): Use do_test instead of do_test_a for rvalue
	range.
	(test_constexpr): Call function template instead of just
	instantiating it.
	* testsuite/23_containers/vector/cons/from_range.cc: Use dg-do
	run instead of compile.
	(test_ranges): Fix ill-formed call to do_test.
	(test_constexpr): Call function template instead of just
	instantiating it.
	* testsuite/23_containers/vector/modifiers/append_range.cc:
	Use dg-do run instead of compile.
	(test_constexpr): Likewise.
	* testsuite/23_containers/vector/modifiers/assign/assign_range.cc:
	Use dg-do run instead of compile.
	(do_test): Do not reuse input ranges.
	(test_constexpr): Call function template instead of just
	instantiating it.
	* testsuite/23_containers/vector/modifiers/insert/insert_range.cc:
	Use dg-do run instead of compile.
	(do_test): Fix incorrect function arguments to match intended
	results.
