Neil Roberts 4c82f2c3a9 nir/opt_intrinsics: Fix values for gl_SubGroupG{e,t}MaskARB 
Previously the values were calculated by just shifting ~0 by the
invocation ID. This would end up including bits that are higher than
gl_SubGroupSizeARB. The corresponding CTS test effectively requires that
these high bits be zero so it was failing. There is a Piglit test as
well but this appears to checking the wrong values so it passes.

For the two greater-than bitmasks, this patch adds an extra mask with
(~0>>(64-gl_SubGroupSizeARB)) to force these bits to zero.

Fixes: KHR-GL45.shader_ballot_tests.ShaderBallotBitmasks
