* unknownify accesses * Move to simplify to break less with fewer changes * Accept baselines for now * Always propegate any as an index type * Fix flow control in the presence of simplifiable types * Add spy repro from #25181 * Retain errorType when it is used as a marker for the lack of a constraint * Small refinement * Add new test * Move most potentially recursive types from isIdenticalTo into structuredTypeRelatedTo to match the non-identity relations * Fix nits * Doesnt need to be undefineable at all
