glsl: ignore all but the rightmost layout-qualifier-name
When a layout contains a duplicated layout-qualifier-name in a single declaration, only the last occurrence should be taken into account. From page 59 (page 65 of the PDF) of the GLSL 4.40 spec: " More than one layout qualifier may appear in a single declaration. Additionally, the same layout-qualifier-name can occur multiple times within a layout qualifier or across multiple layout qualifiers in the same declaration. When the same layout-qualifier-name occurs multiple times, in a single declaration, the last occurrence overrides the former occurrence(s)." Consider this example: " #version 150 #extension GL_ARB_enhanced_layouts: enable layout(max_vertices=2, max_vertices=3) out; layout(max_vertices=3) out;" Although different values for "max_vertices" results in a compilation error. The above code is valid because max_vertices=2 is ignored. When merging qualifiers in an ast_type_qualifier, we now simply ignore new appearances of a same layout-qualifier-name if the "is_single_layout_merge" parameter is true, this works because the GLSL parser processes qualifiers from right to left.
