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."

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."
