[Piglit] [PATCH 1/4] Tests that a pre-declared struct can be used in an interface block.

[Nicholas Mack]

GLSLang// GLSLangSpec.1.50.11, 4.3.7 Interface Blocks:
"built-in types, previously declared structures, and arrays of these
are allowed as the type of a declarator in the same manner they are
allowed outside a block."
