Microbenchmark input data

This microbenchmark replicates the access pattern of cl when compiling
one particular file from chromium/base.
Run it like this:
  sh winetricks vc2005trial psdkwin7
  i586-mingw32msvc-gcc open.c
  time wine a.exe < open.in
It runs in 0.3 seconds normally on Wine, but 0.2 seconds with the bloom filter
patch applied.  I think that's enough to explain at least part of the slowdown.
