Erik, I think we'd want the hole series minus the ES extension?

The issues fixed with the final patch affect GLSL 1.30-4.60 at least.
Even if there's no desktop gl tests for it.

12f001f013c glsl: add has_implicit_conversions()-helper
e975c5b785f glsl: add has_implicit_uint_to_int_conversion()-helper
ecab2d6f148 glsl: fall back to inexact function-match
742dace8251 glsl: do not allow implicit casts of unsized array initializers
