Fix the leak by freeing the file->path in destroy_cpp_file.
However, doing so would lead to a use-after-free in input.c's file cache
since the filenames in this cache are the libcpp file->path buffers.

Hence we need to ensure that any references to the file in the input.c
cache are purged before cleaning up file->path.  This is normally done
by the temp_source_file dtor.  Hence we need to reorder things to that
the temp_source_file dtor runs before cleaning up the cpp_parser.  The
patch does this by introducing a wrapper class around cpp_parser *, so
that the dtor can run after the dtor for temp_source_file.

gcc/ChangeLog:
	* input.c (fcache::file_patch): Add comment about lifetime.
	(selftest::cpp_reader_ptr): New class.
	(selftest::lexer_test): Convert m_parser from cpp_reader *
	to a cpp_reader_ptr, and move m_tempfile to after it.
	(selftest::lexer_test::lexer_test): Update for above reordering.
	(lexer_test::~lexer_test): Move cleanup of m_parser to
	cpp_reader_ptr's dtor.
