bjorn3 16afefdab1 Some refactorings to the ISLE parser (#5693 )

* Use is_ascii_digit and is_ascii_hexdigit in the ISLE lexer

* Use range pattern in ISLE lexer

* Use a couple of shorthands in the ISLE parser

* Use parse_ident instead of symbol + str_to_ident

* Introduce token eating api

This is a non-fatal version of the take api

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.
