Switches the SVM tests to the new test registration framework.
The first commit is the best to review and contains the actual changes.
The second commit purely has formatting changes.
Note that several of these changes were a bit more than mechanical
because many of the SVM tests create a new context vs. using the context
provided by the harness and passed to each test function. The previous
code named the context provided by the harness differently, and hence
could use the name "context" in each test function, but with the new
test registration framework this is no longer possible. Instead, I am
creating the new context using the name "contextWrapper" and then
assigning it to the "context" passed to the test function, which seems
like the best way to avoid using the wrong context unintentionally. I am
open to suggestions to do this differently.
I have verified that the same calls are made before and after these
changes, and specifically that there are no context leaks.
Isuue #875 clarified that CL_INVALID_BUFFER_SIZE should be returned if
clCreateBuffer is passed a pointer returned by clSVMAlloc as its
host_ptr and the size of the buffer exceeds the size of the SVM
allocation.
Add a new negative test to ensure CL_INVALID_BUFFER_SIZE is returned
when the size of buffer exceeds the size of the SVM allocation.
Fixes#1701
