Subject: fixup global generic parameters 1. simplify RoundUpToAlignment() 2.
 add new a render-compute test case to cover the situation where the
 entry-point interface (parameter/return types of an entry-point function) is
 dependent on the global generic type. 3. initial fixes to get this test case
 to compile (but is not producing correct HLSL output yet)
