    [intel] Use the memory type mask containing the caching flags.

    Set correct flags mask when validating buffers.
    
    The 'mask' value used in the validation operation specifies which of the
    'flags' bits are being modified. Buffer validation wants to pass the memory
    type and access mode (rwx) to the kernel so that the buffer will be placed
    correctly, and so that the right kind of fence will be created (read vs
    write). That means we actually want a constant mask for these operations,
    and not something computed from the bits coming in. The constant we want is
    DRM_BO_MASK_MEM | DRM_BO_FLAG_READ | DRM_BO_FLAG_WRITE | DRM_BO_FLAG_EXE.

    [965] Improve performance by including reloc target buffer pointers in keys.
    
    Without this, the WM binding tables would all collide, for example.  Improves
    openarena performance by around 2%.
