Change generation of specs split on match cases so the requires uses `match` also. The change in avanhatt#101 is actually broken, though it did't trigger any errors because the specs are unused on the main branch. When working on avanhatt#99 the error does manifest. Specifically, the error is in the generated requires clauses: https://github.com/mmcloughlin/veriisle-wasmtime/blob/432bd4a86635cd82c76857689ff67c77e99cbd4e/cranelift/codegen/src/isa/aarch64/spec/loads.isle#L111-L113 This references the variable `extendop`, which does not exist. It doesn't exist because it's a field of the enum variant, and we haven't brought its fields into scope. This change updates the match case spec generation to use a match in the requires as well. This is probably a cosmetic regression avanhatt#62. If we care to we could update this in future to only use a match statement in the case where the child requires accesses the variable, but it doesn't seem worth it for now. Updates #35 avanhatt#48

Introduces an explicit unspecified type in the spec language. This is motivated by work to model memory operations avanhatt#99, and in particular the use of the `AMode` enum and its many variants. Some of the variants are unused at the moment. The unspecified type is intended to allow us to define _some_ model for them, and therefore satisfy type inference. However, unspecified type is not allowed to be used for anything non-trivial, so we would be alerted in future if we need to revise the model to a correct type. Updates avanhatt#48 avanhatt#49

Derive type constraints for struct types. This now allows an `instantiate` directive for example to contain a struct field. This arises in avanhatt#99 when specifying the type instantiations of a `load`, which takes `MemFlags`. Updates avanhatt#49

This PR implements the implies
=>spec operator.Note this operator already exists in the annotation IR and veri IR levels, so
this PR just does the plumbing to connect up to the parser.
