I guess when the change to add the convergence token was first introduced it
was important to check that the convergence token was correctly generated for
the appropriate spirv operations. But now it is probably quite redundant to add
that on each test, and checking for the convergent attribute is sufficient.
Will update to use `-DTARGET` as suggested.
