To improve performance, this patch makes Promise.all and Promise.race not
perform correct catch prediction when the debugger is not open. The case
may come up if Promise.race or Promise.all is called, then DevTools is
open, then a component Promise is rejected. In this case, the user would
falsely get an exception event even if the "pause on caught exceptions"
box is unchecked. There are tests which triggered this case; however, it
seems both unlikely and and acceptable to have an event in this case.
Many analogous events are already produced when DevTools is enabled
during the operation of a program.
