This commit adds the `wasmtime settings` command to print out available Cranelift settings for a target (defaults to the host). The compile command has been updated to remove the Cranelift ISA options in favor of encouraging users to use `wasmtime settings` to discover what settings are available. This will reduce the maintenance cost for syncing the compile command with Cranelift ISA flags.
This crate contains the metaprogram used by cranelift-codegen. It's not useful on its own.
