[Piglit] [PATCH 1/2] GLSL-1.50 compiler: Test that vertex shader inputs can be arrays

[Steve Miller]

 * GLSLLangSpec.1.50.09 4.3.4 Inputs:
 *  Vertex shader inputs can only be float, floating-point vectors, matrices,
 *  signed and unsigned integers and integer vectors.Vertex shader inputs can
 *  also form arrays of these types, but not structures
