    i965: Fix MRF register number assertions for compr4.

    compr4 is represented by setting the high bit on the MRF number.
    We need to mask it out before sanity checking the register number.

    Fixes ~8000 assert fails on Ironlake and G45.

I decided just to push the patch because it was a simple mistake with an
obvious fix, and I'd rather not leave every GL program on G45/ILK broken longer
than I have to :)
