Detailed Description

This pass exposes codegen information to IR-level passes.

Every transformation that uses codegen information is broken into three parts:

1. The IR-level analysis pass.
2. The IR-level transformation interface which provides the needed information.
3. Codegen-level implementation which uses target-specific hooks.

This file defines #2, which is the interface that IR-level transformations use for querying the codegen.
