Value number TypeHandleToRuntimeType helper
This is a pure helper w/o side-effects, so add it to the lists of
tractable helpers in value-numbering; this allows redundant calls to be
CSEd, and fixes #9552 so we can again optimize away type checks on type
parameters in generic code (a not-infrequent pattern).
