GPU Foreach Loop (#1498)

* GPU Foreach Loop

This PR introduces the completed GPU foreach loop and updates the
heterogeneous-hello-world example to use it.  This PR builds on the
previous introduction of the GPU Foreach loop parsing and semantic
checking PR (#1482) by introducing IR lowering and emmitting.  THe new
feature can be used by having a GPU_Foreach loop interacting with a
named non-CPP entry point, and using the -heterogeneous flag.

* Fix to path
