[Piglit] [PATCH] glsl: Compile test precision qualifiers on structure members

[Ian Romanick]

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

Section 4.1.8 (Structures) of both the GLSL ES 1.00 spec and GLSL 1.30
specs says:

    "Member declarators may contain precision qualifiers, but may not
    contain any other qualifiers."

However, at some point this stopped working in Mesa.  These tests
current fail on Mesa master and 9.2, but they both pass on the 9.1
branch.
