[Piglit] [PATCH 2/8] gen_builtin_uniform_tests.py: Declare how big of a window we actually need.

[Eric Anholt]

compare-perf of fs-op-mult-vec4-vec4.shader_test for VC4 simulation
shows -95.8062% +/- 1.57425% effect on runtime (n=5).  No difference
proven on i965 with piglit-run.py -t
glsl-1.10/execution/built-in-functions/fs-op (n=14).
