These are due to builtins.h.  The structs defined in there need
FIRST_PSEUDO_REGISTER.  This means that we have parts of builtins.h
that are OK for FEs and others that aren't.  This is not good.

The best alternative for this change is to leave the declarations for
builtins.h inside tree.h and then decide what to do about builtins.h
itself. We clearly need it to declare everything related to builtins,
but from what you're stating about tm.h, we will need to have an FE
variant and an ME/BE variant?
