i965: Fix GPU hangs on Broadwell in shaders with some control flow.
According to the documentation, we need to set the source 0 register
type to IMM for flow control instructions that have both JIP and UIP.
Fixes GPU hangs in approximately 10 Piglit tests, 5 es3conform tests,
Unigine Crypt, a WebGL raytracer demo, and several Steam titles.
Topi, Kristian, and I all verified the fix.</pre>
