Jamey Sharp 2688b44915 cranelift-isle: Factor out rule/pattern/expr visitors (#5174 )

This makes some rather tricky analysis available to other users besides
the current IR. It shouldn't change current behavior, except if a rule
attempts to bind its root term to a name. There's no Rust value for a
root term, so the existing code silently ignored such bindings and would
panic saying "Variable should already be bound" if a rule attempted to
use such bindings. With this commit, the initial attempt to bind the
name reports the error instead.

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.
