Chris Fallin 56236fb58e ISLE: fix compile fuzz target, and fix a simple error-reporting bug. (#3845 )

It seems our `compile` fuzz target for ISLE has not been regularly
tested, as it was never updated for the `isle` -> `cranelift_isle` crate
renaming. This PR fixes it to compile again.

This also includes a simple fix in the typechecking: when verifying that
a term decl is valid, we might insert a term ID into the name->ID map
before fully checking that all of the types exist, and then skipping
(for error recovery purposes) the actual push onto the term-signature
vector if one of the types does have an error. This phantom TID can
later cause a panic. The fix is to avoid adding to the map until we have
fully verified the term decl.

ISLE: Instruction Selection / Lowering Expressions

ISLE is a domain specific language (DSL) for instruction selection and lowering clif instructions to vcode's MachInsts in Cranelift.

ISLE is a statically-typed term-rewriting language. You define rewriting rules that map input terms (clif instructions) into output terms (MachInsts). These rules get compiled down into Rust source test that uses a tree of match expressions that is as good or better than what you would have written by hand.
