(find_shift_sequence): Remove the read_reg argument and return the
read value. Emit the instructions instead of returning them.
Iterate on new_mode rather than calculating it each time.
Check MODES_TIEABLE_P. Use simplify_gen_subreg to convert the
source to NEW_MODE and extract_low_bits to convert the shifted
value to READ_MODE.
(replace_read): Allow the load and store to have different mode
classes. Use extract_low_bits when SHIFT == 0. Create the shift
or extraction instructions before trying the replacement. Update
dump-file code accordingly, avoiding use of REGNO (store_info->rhs).
