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.

* cselib.cc (new_cselib_val): Skip BImode while keeping track of
subvalue relations.
