[Piglit] [PATCH] arb_gpu_shader_int64: generate int64 conversion tests.

Mon Jun 20 05:05:39 UTC 2016
From: Dave Airlie <airlied at redhat.com>
This is "ported" from the fp64 conversion generator, it
probably has a lot of stuff left over it shouldn't, but it
does generate the tests I expected to test 64-bit integer
conversions both implicit and explicit.
