I forgot to update the commit message to include the info from the bug:

"Fixes Piglit's spec/arb_compute_shader/linker/bug-93840 on Ivybridge GT1
 and Baytrail."

That Piglit test hits the 12k limit on IVB GT1 and Baytrail, which have
to use SIMD32 mode.  (IVB GT2 has enough threads that it can get away
with SIMD16 mode and doesn't spill as much.)

I believe I tried clamping the 2MB limit to something smaller so that it
would actually hit this code, and it worked.
