[Bug c++/35004] New: Adding 4 more tree codes causes a crash in building libstdc++ pre-compiled headers

[michael dot meissner at amd dot com]

If I add 4 more tree codes to tree.def, it causes a segmentation violation in
building libstdc++ pre-compiled header files.

Here is the patch to add 4 more tree codes:
