With BytecodeArray flushing the SFI->BytecodeArray pointer will become pseudo weak.
Instead of getting the bytecode array from the SFI, get it from the frame instead
(which is a strong pointer). Note: This won't actually change behaviour since the
fact that the bytecode array was on the frame will retain it strongly, however it
makes the contract that the BytecodeArray must exist at these points more explicit.
Updates code in runtime-profiler.cc, frames.cc and runtime-test.cc to do this.
