[Piglit] [PATCH] arb_bindless_texture: add test for conversion of bounded sampler2D to uvec2

[Karol Herbst]

conversion of bounded sampler2D to uvec2 is legal with
ARB_bindless_texture. Currently Mesa fails with an assert:

../src/compiler/glsl/opt_function_inlining.cpp:248:
void ir_call::generate_inline(ir_instruction*): Assertion `deref' failed.
