The test includes two ssbos, with the same content but different
layouts, in order to ensure that works in both cases.

Note that std140 and std430 layouts are used on the base GLSL shader
used to generate the SPIR-V shaders. SPIR-V shaders doesn't include
info about the layout. From ARB_gl_spirv spec:

    "Mapping of layouts

      std140/std430 -> explicit *Offset*, *ArrayStride*, and
                         *MatrixStride* Decoration on struct members"

So the SPIR-V generated may have different explicit
offset/strides. For this test we include types on the ssbo that gets
different offsets/strides based on the layouts.
