X87: [runtime] Fix ES6 9.2.1 [[Call]] when encountering a classConstructor.

X87: [runtime] Fix ES6 9.2.1 [[Call]] when encountering a classConstructor.

  port ab84025977fb94bebf7d4d83b874da5a6c1c6293 (r31790).

  original commit message:
  The current implementation of classes throws the TypeError at the wrong
  point, after activating a new context when directly calling a class
  constructor. According to the spec, the TypeError has to be thrown
  in the caller context.
