  46d27dd... Fix a couple of memory leaks in the C++ frontend

commit 46d27ddd2bc3e4e2de9be5a3bb732f2bcb38365a
Author: Patrick Palka <ppalka@gcc.gnu.org>

    Fix a couple of memory leaks in the C++ frontend
    
    These were detected with valgrind.  The leak in get_mapped_args is due
    to auto_vec not properly supporting elements of non-trivial type.
    
    Is this okay to commit after bootstrap + regtest succeeds on
    x86_64-pc-linux-gnu?
    
    gcc/cp/ChangeLog:
    
    	* constraint.cc (get_mapped_args): Avoid using auto_vec
    	as a vector element.  Release the vectors inside the lists
    	vector.
    	* parser.c (cp_literal_operator_id): Free the buffer.
