    [intel] Add a single-entry relocation buffer cache.
    
    By avoiding the repeated relocation buffer creation/map/unmap/destroy for each
    new batch buffer, this improves OpenArena framerates by 30%.  Caching batch
    buffers themselves doesn't appear to be a significant performance win over
    this change.

    [intel] Convert relocations to not be cleared out on buffer submit.
    
    We have two consumers of relocations.  One is static state buffers, which
    want the same relocation every time.  The other is the batchbuffer, which gets
    thrown out immediately after submit.  This lets us reduce repeated computation
    for static state buffers, and clean up the code by moving relocations nearer
    to where the state buffer is computed.
