PIC_OFFSET_TABLE_SAVE_RTX in large stack frame

I believe that my revision does this.  The save is done once prior to
the first call.  The save is in the normal insn stream.  The rtl for the
save is generated when the initial rtl is generated, not deferred until
the save RTX gets a hard register or stack slot.  Thus, I think it doesn't
have the same problem with large frames that Alan's does.  I am trying
to set up to do a glibc build with it.
