* Implement intrinsics for the Subzero backend required for
ANGLE / SwiftShader for GLES 2 and 3.
* Note that most intrinsics are implemented as "emulated". I've added
rr::emulated namespace in EmulatedReactor.hpp/cpp that contains the set
of Reactor functions that are presently being emulated. These are
invoked from SubzeroReactor until we decide to implement proper
intrinsics for these in Subzero.
