PING: PATCH: Do not clear the DECL_BIT_FIELD flag (prelude to ObjC fix)

[Richard Kenner]

    Judging from Richard Henderson's earlier e-mail, it is not clear to
    me whether not clearing DECL_BIT_FIELD will affect codegen.  This is,
    I think, the question that needs to be answered.  Alas, I'm in no
    position to answer it. :-(

It will certainly *affect* it.  RTH's claim is just that there is
least one place where it might not matter, not that *all* places are such.
