[mlir] Prevent implicit downcasting to interfaces
ClosedPublic

Authored by rkayaith on Apr 16 2023, 9:39 PM.

Details

Summary

Currently conversions to interfaces may happen implicitly (e.g.
Attribute -> TypedAttr), failing a runtime assert if the interface
isn't actually implemented. This change marks the Interface(ValueT)
constructor as explicit so that a cast is required.

Where it was straightforward to I adjusted code to not require casts,
otherwise I just made them explicit.

Depends on D148491, D148492

Not sure if this is the best way to do this, I couldn't figure out how to get DRR to do the cast.
