Switch from recursing into non-canonical instruction fields to separately canonicalizing those fields. This means we now form canonical `InstBlockId`s, `TypeBlockId`s, `IntId`s, `FloatId`s, and `BindNameId`s at least in the cases when they're referenced by a constant instruction. This reduces the overall runtime for @chandlerc's 10MLoC example by 27.5% on my machine.
