  SVN rev 182170 on 2008-08-25 19:06:02Z by jkim
  MFC:    Sync. BPF JIT compiler with HEAD.
  - r179967, r179968, r179977, r179978:
  Rehash and clean up BPF JIT compiler macros to emit opcodes closer
  to GNU as(1) generated codes and micro-optimize.
  - r181644, r181645:
  Replace number of stack usages with registers.  Note amd64 version
  does not use stack any more because it has more registers.
  - r181697:
  Remove unnecessary jump instructions of zero offsets.
  - r181700, r181848, r181853:
  Correctly check unsignedness of all registers used for load instructions
  with (in)direct offsets and sync. with sys/net/bpf_filter.c
  - r181648, r181649, 181846:
  Update copyrights, fix style(9) nits, remove unused macros, and make
  JIT compilers compilable on user land.
