Summary: This intrinsic returns true if the current thread belongs to a live pixel and false if it belongs to a pixel that we are executing only for derivative computation. It will be used by Mesa to implement gl_HelperInvocation. Note that for pixels that are killed during the shader, this implementation also returns true, but it doesn't matter because those pixels are always disabled in the EXEC mask. This unearthed a corner case in the instruction verifier, which complained about a v_cndmask 0, 1, exec, exec<imp-use> instruction. That's stupid but correct code, so make the verifier accept it as such.
