Detailed Description

A class that saves hashes and textual IR snapshots of functions in a SandboxIR Context, and does hash comparison when expectNoDiff is called.

If hashes differ, it prints textual IR for both old and new versions to aid debugging.

This is used as an additional debug check when reverting changes to SandboxIR, to verify the reverted state matches the initial state.
