New Revision: 242096
Add more subreg offset helpers
Provide versions of subreg_lowpart_offset and subreg_highpart_offset
that work on mode sizes rather than modes. Also provide a routine
that converts an lsb position to a subreg offset.
The intent (in combination with later patches) is to move the
handling of the BYTES_BIG_ENDIAN != WORDS_BIG_ENDIAN case into
just two places, so that for other combinations we don't have
to split offsets into words and subwords.
