pan/mdg: Reexpress umul_high packing

There are a bunch of subtle details of how 32-bit sources are
zero-extended to 64-bit, how their swizzles work, how 64-bit
destinations are shrunk to 32-bit, and how those two interact. This
fixes the interactions... mostly.

Fixes umul_high, all such tests should be passing now. Unblocks idiv
lowering that depends on umul_high.
