No. Indeed, it can hurt, since using gen_lowpart helps arrange
for proper debugging information to be generated. I.e. it updates
the REG_ATTRS information properly.
I'm sure there's lots of backends that could do well to not JUST
call gen_rtx_REG (mode, REGNO (x)). Using gen_rtx_REG_offset
instead would be much preferred.
