Pull Request Overview
This PR implements the getAsyncInfo callback in the ILCompiler's JIT interface to support async method compilation in ReadyToRun scenarios. The implementation aligns with CoreCLR's definition by expanding the CORINFO_ASYNC_INFO structure and providing concrete field and method handle lookups.
Key Changes:
- Extended
CORINFO_ASYNC_INFOstructure with additional fields for async state management - Implemented the
getAsyncInfomethod to populate async continuation and context management handles - Added support for execution context capture/restore operations in async workflows
