John Stiles 2af4b13925 Reject programs which exceed 50 stack frames during size analysis. 
Our program-size analysis pass needs to recurse into called functions;
depending on the exact order of functions in the program, this recursion
can hypothetically be as deep as the deepest function-call chain. Set an
upper bound on recursion here, so we don't overflow the stack while
trying to check the program size. In practice, 50 frames is far deeper
than a regular shader should ever go.
