Jamey Sharp bfc6aad184 cranelift-isle: codegen from new IR (#5435 )

ISLE's existing code-generation strategy doesn't generate the most
efficient matching order for rules. This PR completely replaces it.

With this PR applied, wasmtime compile retires 2% fewer instructions on
the pulldown-cmark and spidermonkey benchmarks from Sightglass.

A dev build of cranelift-codegen from an empty target/ directory takes
2% less time. The build script, invoking ISLE, takes a little longer,
but Rust can compile the generated code faster, so it balances out.

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.
