Erik Eckstein 8a8a895239 alias analysis: compute more precise memory effects of builtin "once"
* Check if the address in question is even visible from outside the function
* Return the memory effects of the called function

Also, add a new API `Instruction.memoryEffects`, which is internally used by `mayReadFromMemory` et al.
