commit 6a3d77e13dbae17000e35ce16023532200e68d09

    softpipe: Shrink context size.

    - each softpipe_tex_tile_cache 50*64*64*4*4 = 3,276,800 bytes
    - each softpipe_context has 3*32 softpipe_tex_tile_cache, i.e, each
softpipe
      context is 314,572,800 bytes, i.e, 300MB

    That is, in a 32bits process (around 3GB virtual memory max), we can
    only fit 10 contexts.

    This change is a short-term hack to shrink the context size.  Longer
    term we'll need to change how the texture cache works.
