2025-02-11gccrs: add discriminant value intrinsicPhilip Herron11-62/+235
This is pretty nasty piece of rust in my opinion the return type of this intrinsic results into a lang item associated type: <T as DiscriminantKind>::Discriminant This is a special case which needs to support mapping onto the repr type of the associated ADT that is passed in, but defaults to iszie otherwise. This patch assumes we only come accross this case in a HIR::CALL_EXPR, so and makes assumutions that its always of this function signiture. I will do some checking in libcore to verify that assumption.
