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.
