Bug detailed description:
-------------------------
Run the glean test case glsl1 with the mesa glsl2 branch's code, it will has some error info as folowing. Many folowing test cases are affected by it. 

intel_bufmgr_gem.c:1098: Error setting domain 9: Input/output error intel_bufmgr_gem.c:1098: Error setting domain 9: Input/output error intel_bufmgr_gem.c:1098: Error setting domain 9: Input/output error intel_bufmgr_gem.c:1098: Error setting domain 9: Input/output error intel_bufmgr_gem.c:1098: Error setting domain 9: Input/output error intel_bufmgr_gem.c:1098: Error setting domain 9: Input/output error intel_bufmgr_gem.c:1098: Error setting domain 9: Input/output error intel_bufmgr_gem.c:1098: Error setting domain 9: Input/output error

----------------
1. xinit & 
2. ./glean -r glsl1 -o --quick -v -v -v -t glsl1

Appending this to all.tests works around the problem for now:

profile.tests['glean']['glsl1-for-loop with continue'].env['LIBGL_ALWAYS_SOFTWARE'] = 1

    glsl2: When a "continue" happens in a "for" loop, run the loop expression.
    
    Fixes:
    glsl1-for-loop with continue

With the newest code(3e882ec84a2493da74c55d105010a37de521e593) on mesa glsl2 branch, glean/glsl1 will not hang GPU now and it doesn't affect other tests. So verified.
