- Validate that hipGetErrorString returns a non empty string for all error enumerators
- Negative parameter test for hipGetErrorName and hipGetErrorString
- Validate expected behaviour of hipGetLastError and hipPeekAtLastError
- Multithreaded tests for hipGetLastError and hipPeekAtLastError
- Remove threaded_zig_zag_test.
- Validate error string for invalid error enumerator
