[Piglit] [PATCH 1/1] Add tests/spec/glsl-es-1.00/execution/maximums shader tests

[Tom Gall]

Adds gl_MaxCombinedTextureImageUnits.shader_test
     gl_MaxDrawBuffers.shader_test
     gl_MaxFragmentUniformVectors.shader_test
     gl_MaxTextureImageUnits.shader_test
     gl_MaxVaryingVectors.shader_test
     gl_MaxVertexAttribs.shader_test
     gl_MaxVertexTextureImageUnits.shader_test
     gl_MaxVertexUniformVectors.shader_test

These check the built-in constants of the same name from
section 7.4 of the glsl es 1.0.17 spec.

v2: squash patch, address one by one spec reference.
