Richard Smith 5c8fa6ad5c Replace FoldingSet with DenseMap for instruction canonicalization. (#3979) 
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.
