Matt Pharr 748b292e77 Improve code for uniform switches with a 'break' under varying control flow. ...

Previously, when we had a switch statement with a uniform switch condition
but a 'break' statement that was under varying control flow inside the
switch, we'd promote the switch condition to be varying so that the
break would work correctly.

Now, we leave the condition as uniform and are thus able to use the
more-efficient LLVM switch instruction in this case.

Issue #156.
