[Piglit] [PATCH] arb_gpu_shader_fp64: test passing an array from vs->gs->fs works.

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

This adds two variants on the same basic test, passing
an array of values from vs->gs->fs. The second variant
just initialised the array from 64-bit attributes.
