Speculative BigInt addition fails to throw the expected exception
when called with non-BigInt inputs when the result of the computation
is unused. In paricular, this CL does:
 - Remove kNoThrow on speculative BigInt operators
 - Fix AddWithFeedback to not lose type feedback if builtin throws
   to elide existing deopt loops
 - Add handling of TypeCheckKind in RepresentationChanger where this
   was previously ignored
