NVCC improvements.

- Complete translation tables for cudaError <-> hipError_t.
- Remove some odd errors that were not correctly translated or not used.
- Add HIPCHECK_API to test infrastructure.  Used for negative testing
  an API ; if a mismatch occurs it shows the expected return error
  code.  Can also print a warning rather than error.
- Enable hipMemoryAllocate on NV system, and review error coded.
- Add hipErrorName to nvcc.

Bug fixes and improved docs for hipFree and hipHostFree.

    - Passing NULL pointer initialized runtime and return hipSuccess
      (not an error like before).
    - add negative test for this. (hipMemoryAllocate, improved)
    - Match NVCC errors for invalid pointers, add to test.
    - Update hipFree and hipHostFree docs.
    - hipGetDevicePointer always set *devicePointer=NULL, even for
      invalid flags.
    - Gate shared memory usage on specific HCC work-week.
