Re: [PATCH]: Move FIELD_DECL into it's own structure

I misspoke, we have macros for a large number of non-positive checks, we
only use them in one place :)

This is still true, however, because we have PARM_DECL_CHECK, etc.

If you inherited from VAR_DECL, for example, you'd fail attempting to
right now.

If you want to do better on checking, the easiest thing to do about
inheritance would be to change the classes to include the subclasses,
but this is tricky.
I'd rather do that as a step 2 or followup after splitting a couple of
these decls, and seeing whether we really want to do this.

By this i mean i'm happy to change the current DECL_CHECK macros to be
all positive checks for *all decls* but FIELD_DECL right now, instead of
tcc_declaration - FIELD_DECL.

As i go through all the _DECL's and discover what's really going on, i'm
happy to remove the approriate code's from those macros.
