Original Patch and summary by Philip Reames. RewriteStatepointsForGC tries to rewrite a function in a manner where the optimizer can't end up using a pointer value after it might have been relocated by a safepoint. This pass checks the invariant that RSForGC is supposed to establish and that (if we constructed semantics correctly) later passes must preserve. This has been a really useful diagnostic tool when initially developing the rewriting scheme and has found numerous bugs.
