Setting this flag prevents declarations of uniforms from being removed
from the IR. Since the IR is directly used by several API functions
that query uniforms in shaders, uniform declarations cannot be removed
after the locations have been set. However, it should still be safe
to reorder the declarations (this is not tested).

I applied these two patches to my tree but I'm still seeing the
GL_INVALID_OPERATION error in glUniform() calls that I mentioned in
the bug report (param->DataType = 0).
The viewperf test I'm using has a fairly complex vertex shader with an
array of structures of lighting info containing a "vec3 position" field.
The test calls glGetUniform(shader, "LW_LightSource1[0].position").
When glUniform3f() is called to set that uniform, the
GL_INVALID_OPERATION errro is raised.
I'll try a bisection to see where this started failing.
