There are now two implementations of printf in HIP: 1. The implemenation for HCC is controlled by the HC_FEATURE_PRINTF macro, and it works only with the HCC compiler used in combination with the HCC runtime. 2. The implementation for hip-clang requires the VDI runtime, and is always enabled with that combination. Change-Id: Ibaeda7900ffe2ce602ca0094aafed0f1147ac2b6
