[PATCH] [gcc-8-branch] Fix recent unique_ptr regressions

[Jonathan Wakely]

These test changes should have been committed with r275193.

	* testsuite/20_util/unique_ptr/assign/48635_neg.cc: Replace dg-error
	with dg-prune-output for enable_if failure.
	* testsuite/20_util/unique_ptr/cons/cv_qual_neg.cc: Add
	dg-prune-output for enable_if failure.

Tested x86_64-linux (properly this time), committed to gcc-8-branch.
