2x40 bit vector modes...

- Subject: 2x40 bit vector modes...
Does anyone know a good reason not to allow modes such as V2PDI? The
Blackfin has dual multiply accumulate to 40 bit registers, and of all
the iffy ways to describe that, something involving 2x40 bit vectors
seems the least ugly.
Or does anyone have a better idea about handling 40 bit modes in general
than using PDImode?
