[RFC] bsd.cpu.mk update for newer processors

Since we have enabled clang by default on current, I'd like to update
bsd.cpu.mk as well.  Please see the attachment.  It is also available
from here:

http://people.freebsd.org/~jkim/cpu.diff

I only added most popular SIMD features to MACHINE_CPU (i.e., sse4a,
sse41, sse42, and avx) and clang-supported archs to CPUTYPE (i.e.,
amdfam10, btver1, bdver1, bdver2, corei7, corei7-avx, and core-avx-i).

Any objection?
