Bug detailed description:
-------------------------
Some Piglit and Ogles2conform cause GPU hang on above system environment.
Following Piglit cases cause GPU hang:
glsl-fs-raytrace-<a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - [965] piglit glsl-fs-raytrace failure due to lack of function calls."
href="show_bug.cgi?id=27060">bug27060</a>
spec/glsl-1.40/uniform_buffer/fs-struct-copy-complicated
spec/glsl-1.40/uniform_buffer/vs-struct-copy-complicated
spec/glsl-1.50/uniform_buffer/gs-struct-copy-complicated
shaders/glsl-fs-vec4-indexing-temp-src-in-nested-loop-combined

spec/glsl-1.30/execution/clipping/vs-clip-distance-bulk-assign
spec/glsl-1.30/execution/varying-packing-mixed-types
shaders/glsl-max-varyings
Following Ogles2conform cases cause GPU hang, then system will be no response:
(GLES20)GL_acos_acos_float_frag_xvary.test
(GLES20)GL_acos_acos_vec2_frag_xvary.test
(GLES20)GL_atan_atan_float_frag_xvary.test
(GLES20)GL_atan_atan_float_vert_xvary.test
(GLES20)GL_atan_atan_vec2_vert_xvary.test
Reproduce steps:
-------------------------
1. run ./bin/glsl-fs-raytrace-<a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - [965] piglit glsl-fs-raytrace failure due to lack of function calls."
