This PR introduces the support for the SPIR-V extension `SPV_INTEL_predicated_io`. This extension adds predicated load and store instructions. Predicated load performs load from memory if predicate is true; otherwise, it uses default_value as a result. Predicated store performs store of value to memory if predicate is true; otherwise, it does nothing.
