REG_EXPR will be 0 for compiled-created temporary variables, but that is
not what you have here. I think that if you find that REG_EXPR is
present in your tests, then it should be reliable.

Moving a macro like TYPE_PTRFN_P into tree.h sounds reasonable, whether
or not the source tree is reorganized.
