piglit layout-column_major-non-uniform regressed on softpipe and llvmpipe.

$ ./bin/glslparsertest tests/spec/arb_uniform_buffer_object/compiler/layout-column_major-non-uniform.frag fail 1.20
Successfully compiled fragment shader tests/spec/arb_uniform_buffer_object/compiler/layout-column_major-non-uniform.frag: 0:21(28): warning: uniform block layout qualifiers row_major and column_major applied to non-matrix types may be rejected by older compilers

Shader source:
// [config]
// expect_result: fail
// glsl_version: 1.20
// require_extensions: GL_ARB_uniform_buffer_object
// [end config]

/* From the GL_ARB_uniform_buffer_object_spec:
 *     "Uniform block layout qualifiers can be declared at global
 *      scope, on a single uniform block, or on a single block member.
 *      At global scope, it is an error to use layout qualifiers to
 *      declare a variable. Instead, at global scope, layout
 *      qualifiers apply just to the keyword uniform and establish
 *      default qualification for subsequent blocks:"
