Log:
Factor out the mode handling in lower-subreg.c

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
hook always returns true; a later patch will add cases in which it can
return false.
