cselib: Skip BImode while keeping track of subvalue relations [PR107088]

For BImode get_narrowest_mode evaluates to QImode but BImode < QImode.
Thus FOR_EACH_MODE_UNTIL never reaches BImode and iterates until OImode
for which no wider mode exists so we end up with VOIDmode and fail.
Fixed by adding a size guard so we effectively skip BImode.

gcc/ChangeLog:

	PR rtl-optimization/107088
	* cselib.cc (new_cselib_val): Skip BImode while keeping track of
	subvalue relations.
