Public Member Functions
	IRSnapshotChecker (Context &Ctx)
LLVM_ABI_FOR_TEST void	save ()
	Saves a snapshot of the current state.
LLVM_ABI_FOR_TEST void	expectNoDiff ()
	Checks current state against saved state, crashes if different.

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.
