[Mesa-dev] [PATCH 09/13] glsl: simplified ast_type_qualifier::merge_into_[in|out]_qualifier API

[Andres Gomez]

Since we modified the way in which multiple repetitions of the same
layout-qualifier-name in a single declaration collapse into the
ast_type_qualifier class, we can simplify the
merge_into_[in|out]_qualifier APIs through removing the create_node
parameter.
