evaluating them at compile time rather than at run time. As for x86
and amd64, this requires GCC and it's enabled only if __OPTIMIZE__ is
defined (ie, if at least -O is used).

Their purpose is to give explicit hints to the compiler to judge
the likelyhood of a test to succeed or fail. Not all architectures
have support for such optimizations, but for those who do, it can
give a nice performance improvement in hot loops.
Obviously, this should be used very rarely in very specific code.

MFC after:
the TLB and ~1600 if it is not. Therefore, it is more effecient to
invalidate the TLB after operations that use CMAP rather than before.
- So that the tlb is invalidated prior to switching off of a processor, we
must change the switchin functions to switchout functions.
- Remove td_switchout from the thread and move it to the x86 pcb.
- Move the code that calls switchout into swtch.s. These changes make this
optimization truely x86 specific.
then the mbuf has been consumed by a hook; otherwise beware of a null
mbuf return (gack). In particular the bridge was doing the wrong thing.
While in the ipv6 code make it's handling of pfil_run_hooks identical
to netbsd.

o add ipsec_osdep.h that holds os-specific definitions for portability
o s/KASSERT/IPSEC_ASSERT/ for portability
o s/SPLASSERT/IPSEC_SPLASSERT/ for portability
o remove function names from ASSERT strings since line#+file pinpints
the location
o use __func__ uniformly to reduce string storage
o convert some random #ifdef DIAGNOSTIC code to assertions
o remove some debuggging assertions no longer needed
change 38498
o replace numerous bogus panic's with equally bogus assertions
that at least go away on a production system

o change explicit mtx operations to #defines to simplify
future changes to a different lock type
change 38531
o hookup ipv4 ctlinput paths to a noop routine; we should be
handling path mtu changes at least

o add scan generation # to secpolicy to deal with locking issues
change 38806
o use LIST_FOREACH_SAFE instead of handrolled code
o change key_flush_spd to drop the sptree lock before purging
an entry to avoid lock recursion and to avoid holding the lock
over a long-running operation
o misc cleanups of tangled and twisty code
There is still much to do here but for now things look to be
working again.
