[Piglit] [PATCH] gpu_shader5: Add a test that uses an absurd number of texture arguments

[Jason Ekstrand]

This adds a test that uses an indirect offset into an array of 2D shadow
samplers with a textureProjGradOffset.  The primary purpse of this is to
use a lot of arguments with an indirect offset.  This hits a bug in the
current NIR code where we originally assumed a max of 4 texture arguments.
