We also want to detect a BIV when it corresponds to a variable
whose mode was promoted via PROMOTED_MODE. In that case, an increment
whose mode was promoted. In that case, an increment
of the variable may be a PLUS that adds a SUBREG of that variable to
an invariant and then sign- or zero-extends the result of the PLUS
into the variable.
