add tests for unified SVM corner cases (#2436)

Browse Source 
This PR adds tests for a number of interesting unified SVM corner cases.

Not all of these may be valid tests! If we decide that some of these
tests are invalid, I will remove them.

Added tests include:

* Calling clSVMAllocWithPropertiesKHR to allocate zero bytes for each
unified SVM type.
* Calling clSVMFreeWithPropertiesKHR to free a NULL pointer.
* Calling clEnqueueSVMFree to asynchronously free an empty set of SVM
pointers.
* Calling clEnqueueSVMFree to asynchronously free a NULL pointer.
* Calling clSetKernelArgSVMPointer to set a NULL pointer kernel
argument.
* Calling clSetKernelArgSVMPointer to set a bogus pointer kernel
argument.
* Calling clSetKernelExecInfo with CL_KERNEL_EXEC_INFO_SVM_PTRS with an
empty set of SVM pointers.
* Calling clSetKernelExecInfo with CL_KERNEL_EXEC_INFO_SVM_PTRS with a
NULL pointer.
* Calling clSetKernelExecInfo with CL_KERNEL_EXEC_INFO_SVM_PTRS with a
bogus pointer.
* Calling clEnqueueSVMMemcpy with a size of zero and a NULL source or
destination pointer.
* Calling clEnqueueSVMMemcpy with a size of zero and a bogus source or
destination pointer.
* Calling clEnqueueSVMMemcpy with a size of zero and a valid source or
destination pointer.
* Calling clEnqueueSVMMemFill with a size of zero and a NULL destination
pointer.
* Calling clEnqueueSVMMemFill with a size of zero and a bogus
destination pointer.
* Calling clEnqueueSVMMemFill with a size of zero and a valid
destination pointer.
* Calling clEnqueueSVMMigrateMem with a size of zero and a NULL pointer.
* Calling clEnqueueSVMMigrateMem with a size of zero and a valid
pointer.
