Nate Chandler 6bbc96b8c8 [IRGen] Added fn ptr to async FunctionPointer. ...

The address of the function to be called when generating code to invoke
the function associated with FunctionPointer which is produced via
direct reference is by definition statically known; it is neither necessary
nor desireable to load this address out of the AsyncFunctionPointer
corresponding to the function.

Here, that spurious additional work is skipped.  The approach is to add
a second value to the FunctionPointer struct.  For FunctionPointers
whose kind is AsyncFunctionPointer, this value is either null or else
the address of the corresponding function.
