AFAIK this directly comes from the Ada front-end. Maybe we can tweak
it in gigi, but this has worked like that since day #1 I think.
I'm pretty sure I recall discussions where it was felt that the proper thing
was to keep TYPE_PRECISION equal to the bitsize of TYPE_MODE. On the other
hand, if we always do that, what's the point of TYPE_PRECISION. So I'm
open to doing things here as long as we're consistent.
