i965/fs: Add support for "if" statements in 16-wide mode on gen6+.

It turns out there's nothing in the hardware preventing this.  It
appears that it ought to work on pre-gen6 as well, but just produces
GPU hangs.

Improves glbenchmark Egypt framerate 4.4% +/- 0.3% (n=3), and Pro by
2.6% +/- 0.6% (n=3).
