* Introduce a `TargetFrontendConfig` type. `TargetFrontendConfig` is information specific to the target which is provided to frontends to allow them to produce Cranelift IR for the target. Currently this includes the pointer size and the default calling convention. The default calling convention is now inferred from the target, rather than being a setting. cranelift-native is now just a provider of target information, rather than also being a provider of settings, which gives it a clearer role. And instead of having cranelift-frontend routines require the whole `TargetIsa`, just require the `TargetFrontendConfig`, and add a way to get the `TargetFrontendConfig` from a `Module`. Fixes #529. Fixes #555.
This crate provides a straightforward way to create a
Cranelift IR function and fill it with
instructions translated from another language. It contains an SSA construction
module that provides convenient methods for translating non-SSA variables into
SSA Cranelift IR values via use_var and def_var calls.
