Ian Romanick 945fb51fb5 intel/fs: Fix gl_FrontFacing optimization on Gfx12+ 
It's not obvious why the (gl_FrontFacing ? -1.0 : 1.0) case was handled
different for Gfx12+ than for previous generations, and it's not
correct.  It tries to negate the result as an integer, and it does this
before the mask operation that clears the other bits in the value.

When we eventually support dual-SIMD8 dispatch, the other front-facing
bit is in g1.6 at bit 15, so similar code should be possible there.
