[Piglit] [PATCH 3/3] glsl-es-3.00: Verify that predefined macros cannot be undefined

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

Section 3.4 (Preprocessor) of the OpenGL ES Shading Language 3.00 spec
says:

    "It is an error to undefine or to redefine a built-in (pre-defined)
    macro name."

NOTE: These tests currently fail on Mesa.
