Can you bisect this?  It's possible that this commit is responsible:

    R600/SI: Prefer SALU instructions for bit shift operations

    All shift operations will be selected as SALU instructions and then
    if necessary lowered to VALU instructions in the SIFixSGPRCopies pass.

    This allows us to do more operations on the SALU which will improve
    performance and is also required for implementing private memory
    using indirect addressing, since the private memory pointers must stay
    in the scalar registers.

    This patch includes some fixes from Matt Arsenault.

After update to the latest git version everything returned to normal. Thanks.
