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.

Implement ~line_maps ()
line_maps instances such as the global line_table are
GC-managed, but the htab within location_adhoc_data_map.htab
is not GC-managed.
Previously this was deleted manually by a call to
location_adhoc_data_fini within toplev::main.
However, on adding a call to forcibly_ggc_collect after the
selftests, all of the htabs for the various line_tables
created during the selftests start showing up as leaks
in "make selftest-valgrind", e.g.:

This patch removes the manual one-time cleanup in favor of
adding a destructor to class line_maps, which cleans up
the non-GC-managed htab.

With -fpu=neon DI mode shifts are expanded after reload.
With -fpu=neon DI mode shifts are expanded after reload. DI mode registers can
either fully or partially overlap on both ARM and Thumb-2. However the shift
expansion code can only deal with the full overlap case, and generates incorrect

full overlap or no overlap.
