Jamey Sharp f0fccbd18a cranelift-isle: Helpers to get type/term by name (#5241)
This is a common pattern in sema, so factor it out.

Since this version uses `intern` instead of `intern_mut`, it might be a
tiny bit faster when errors occur due to not writing names into maps
then. When no error occurs, ISLE should do exactly the same work with or
without this commit.

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.
