This patch closes a memory leak in async/await where the desugaring was creating a situation analagous to that described in v8:5002. Intermediate Promises were being kept alive, so a long-running loop would cause linear memory usage on the heap. This patch returns undefined to the 'then' callback passed into PerformPromiseThen in order to avoid this hazard. Test expectations are fixed to remove expecting extraneous events which occurred on Promises that are now not given unnecessarily complex resolution paths before being thrown away.
