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 core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
