Description of problem:

Using VSX registers and operations in llvmpipe makes a couple of piglit tests fail on ppc64le


How reproducible:
Configure ppc64le machine to use llvmpipe and run specific piglit tests 

Steps to Reproduce:
1. Configure ppc64le machine to use llvmpipe
2. Run one of the following piglit tests:
   - glsl-kwin-blur-2
   - glsl-orangebook-ch06-bump
   - gl-1.0-blend-func
   - getteximage-formats
   - arb_blend_func_extended-fbo-extended-blend
   - arb_blend_func_extended-fbo-extended-blend-explicit
   - fbo-blending-formats
   - getteximage-formats init-by-rendering
   - fbo-generatemipmap-formats
3. See that the test fails

Actual results:
