Chris Fallin b652ce2fb1 ISLE: add support for multi-extractors and multi-constructors. (#4908 )

* ISLE: add support for multi-extractors and multi-constructors.

This support allows for rules that process multiple matching values per
extractor call on the left-hand side, and as a result, can produce
multiple values from the constructor whose body they define.

This is useful in situations where we are matching on an input data
structure that can have multiple "nodes" for a given value or ID, for
example in an e-graph.

* Review feedback: all multi-ctors and multi-etors return iterators; no `Vec` case.

* Add additional warning suppressions to generated-code toplevels to be consistent with new islec output.

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.
