Change-Id: I9400943f2f02433cb4409b19c0cac3626c2bc454
* Fix bug in LaunchKernel test
Instead of passing the address of the gpu buffer, pass the address
of the pointer that holds the address of the gpu buffer
* Fix hipLaunchKernel's kernarg buffer construction.
The hipLaunchKernel implementation should rely on ihipModuleLaunchKernel
to construct the kernarg buffer correctly based on kernel metadata.
* Fix a bug in get_functions where the Kernel_descriptor wasn't constructed with the correct kernarg layout information.
* Fix a bug in kernarg layout parsing dealing with kernel without any arg
* teach ihipModuleLaunchKernel to handle kernel without any arg
* Add a more interesting test
