Summary: This patch enables .rgba accessors to ext_vector_type types and adds tests for syntax validation and code generation. 'a' and 'b' can appear either in the point access mode or the numeric access mode (for indices 10 and 11). To disambiguate between the two usages, the accessor type is explicitly passed to relevant methods.
