Nathan Froyd 09c6c5db44 add a "raw" function definition interface to cranelift-module (#1400)
* move trap site definitions into cranelift-module

`cranelift-faerie` and `cranelift-object` already have identical
definitions of structures to represent trap sites.  We might as well
merge them ahead of work to define functions via a raw slice of bytes
with associated traps, which will need some kind of common structure for
representing traps anyway.

* cranelift-module: add `define_function_bytes` interface

This interface is useful when the client needs to precisely specify the
ordering of bytes in a particular function.

* add comment about saving files for `perf`

This crate provides module-level functionality, which allow multiple functions and data to be emitted with Cranelift and then linked together.

This crate is structured as an optional layer on top of cranelift-codegen. It provides additional functionality, such as linking, however users that require greater flexibility don't need to use it.

A Module is a collection of functions and data objects that are linked together. Backend is a trait that defines an interface for backends that compile modules into various forms. Most users will use one of the following Backend implementations:

  • SimpleJITBackend, provided by cranelift-simplejit, which JITs code to memory for direct execution.
  • ObjectBackend, provided by cranelift-object, which emits native object files.
  • FaerieBackend, provided by cranelift-faerie, which emits native object files.
