* compiler -march= parameter is changed from native to corei7
so code is always genereted with instructions which are available
on the Nehalem microarchitecture (up to SSE4.2)
* compiler -mtune= parameter is added so code is optimized for
corei7-avx which equals to Sandy Bridge microarchitecture
* set of macros is added which allows run-time detection of available
cpu instructions (e.g. clib_cpu_supports_avx())
* set of macros is added which allows us to clone graph node funcitons
where cloned function is optmized for different microarchitecture
Those macros are using following attributes:
__attribute__((flatten))
__attribute__((target("arch=core-avx2)))
I.e. If applied to foo_node_fn() macro will generate cloned
functions foo_node_fn_avx2() and foo_node_fn_avx512() (future)
It will also generate function void * foo_node_fn_multiarch_select()
which detects available instruction set and returns pointer to the
best matching function clone.

vpp_restart solves the problem of restarting vpp and not exiting until
the new vpp instance is sufficiently established to allow immediate
binary API connections. The point is to avoid using arbitrary "sleep
N" commands e.g. in CSIT shell scripts.
We send SIGTERM to the current vpp process, and expect / depend on the
process-monitor du jour to remove the vpp-api shared-memory segment.
vpp_restart exits w/ status 0 if all is well, non-zero upon failure.
In trying to make vpp_restart reliable, we discovered a
recently-introduced heap corruption bug in .../dpdk/init.c, which
caused vpp to crash on startup once every 20 times on a particular
rig.
If possible, we should check /var/log/syslog for evidence of
unexpected multiple restarts during regression-testing.
