Detailed Description

Format context containing substitutions for special placeholders.

This context divides special placeholders into two categories: builtin ones and custom ones.

Builtin placeholders are baked into FmtContext and each one of them has a dedicated setter. They can be used in all dialects. Their names follow the convention of $_<name>. The rationale of the leading underscore is to avoid confusion and name collision: op arguments/attributes/results are named as $<name>, and we can potentially support referencing those entities directly in the format template in the future. Custom ones are registered by dialect-specific TableGen backends and use the same unified setter.
