    [965] Bug 14314: assertion failure with with !AIGLX and depth=24 visual.

    [965] Fix TTM relocation caching overzealousness.
    
    The failure mode that was a available was:
    reloc 1 -> target_buf
    exec: PRESUMED_OFFSET wrong, buffer migrates, r1 entry updated.
    reloc 2 -> target_buf
    exec: suppose buffer migrates again.  PRESUMED_OFFSET wrong. r2 entry updated.
    reloc 1 -> target_buf
    exec: suppose buffer doesn't migrate.  PRESUMED_OFFSET right. no relocations
          performed.  r1 has stale pointer at original location.
    
    Failures were reported with OGLconform's VBO test and SPECviewperf90, though
    I haven't confirmed that this fixes it.
