Jonathan Wakely 07b990ee23 libstdc++: Fix inefficiency in filesystem::absolute [PR99876]
When the path is already absolute, the call to current_path() is
wasteful, because operator/ will ignore the left operand anyway.

	PR libstdc++/99876
	* src/c++17/fs_ops.cc (fs::absolute): Call non-throwing form,
