* Added cl_khr_fp16 extension support for commonfns test (issue #142, commonfns) * Added missing header due to presubmit check * Corrected radians/degrees ulp calculations + cosmetic fixes * Corrected presubmit code format * Corrections related to code review * Moved string format helper to test_common in separate header * Added clang format for last commit * Corrections related to code review * Modified mix verification procedure for half type to only report max error * Removed redundant condition for logging mix verification * Corrected generator limits for half tests
