Move ck_barrier.h into shared/static object. Add CK_CC_CACHELINE.
...
There is absolutely no benefit to inlining these. Additionally,
explicitly set the alignment of a ck_barrier_combining_group to
a cacheline.

Implemented ck_barrier_combining.
...
This is the software combining tree barrier from the MCS paper. Currently,
it uses a binary tree; it may be changed later to use an n-ary tree.
Validation (combining_validation.c in regressions/ck_barrier/validate)
has also been added.

regressions: Fix livelock condition in ck_barrier regression.
...
Instead of executing a join on the threads, aggregate existing state
of their counters. This can mean one missed increment per thread,
which is not a big deal.

Commit additional x86 changes to make things work.

I'm tempted to conglomorate sexual deviances with Linus and git
right now that are not entirely appropriate. I'm unimpressed.

Factor out some common utility functions.
...
Moved rdtsc and affinity logic to a single file which other
regression tests use. Single point of reference will ease
porting these to future architectures and platforms. Removed
invalid Copyright statement.
Added CK_CC_USED to force some code generation that I found
useful for debugging.
Added ck_stack latency tests and a modified version of djoseph's
modifications to benchmark.h for spinlock latency tests.
