The raw stuff in the patch looks ok to me, it is always used just in the for_eh
case.  The for_eh argument to output_loc_operands should be still also *_skip
and you shouldn't adjust DW_OP_regx and DW_OP_bregx argument if the parameter
is -1.  And the for_eh_or_skip argument needs documentation in the comment
above the function.
Yeah, on powerpc*-* all targets are affected I think, but I guess it is enough
if you test on i?86-*-darwin and powerpc*-*-darwin, one representative for each
of the DWARF2_FRAME_REG_OUT special targets is enough.  On other targets the
macro is a nop...
