Alex Crichton 65930640f8 Bump Wasmtime to 2.0.0 (#4874)
This commit replaces #4869 and represents the actual version bump that
should have happened had I remembered to bump the in-tree version of
Wasmtime to 1.0.0 prior to the branch-cut date. Alas!

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.
