[16/nn] Factor out the mode handling in lower-subreg.c

2017-10-23 Thread Richard Sandiford
This patch adds a helper routine (interesting_mode_p) to lower-subreg.c, to make the decision about whether a mode can be split and, if so, calculate the number of bytes and words in the mode. At present this function always returns true; a later patch will add cases in which it can return false.
