I found bugs with VOIDmode constants that have caused me to recast my
patches to is_widening_mult_rhs_p. They should be logically the same for
non VOIDmode cases, but work correctly for constants. I think

This can happen when you have "DI + SI * SI" - the multiplication will

This patch fixes the case where widening multiply-and-accumulate were
not recognised because the multiplication itself is not actually widening.
This can happen when you have "DI + SI * SI" - the multiplication will
be done in SImode as a non-widening multiply, and it's only the final
accumula
