regressions: Use correct regression for ck_ring_spmc_template.
...
We were previously building the wrong target. This was found out due
to Phil Sorber pointing out that _template.c would have had compilation issues.

ck_ring: Move the ring buffer outside of the ck_ring_t
...
Remove the ring buffer from the struct ck_ring, it is now required to
explicitely pass the ring buffer for enqueue/dequeue. That can be useful for
systems with multiple address spaces.

regressions/ck_ring: Fix use of uninitialized data.
...
Execution history exists such that first thread will dequeue
from an uninitialized ring buffer. The unit test has been
(un)fortunate in that it would busy-wait during dequeue.
Full barrier semantics will enforce visibility.

Immediate use-case is SPMC. Next is MPSC, then I will generalize
to MPMC (unfortunately, I don't have an algorithm that avoids CAS2
yet for MPMC).

Added support for Sun Studio 12 C compiler.
...
build:
- configure step will generate relevant CFLAGS.
- build profiles are for convenience (developers can use themu
for cross-compilation).
regressions:
- Renamed ck_barrier unit tests to work-around behavior
of Solaris linker.
- Adopted use of a PTHREAD_CFLAGS variable.
ck_cc:
- Added internal CK_CC_IMM macro for compilers that are
verbose against impossible inline constraints (or limited
optimizers).
ck_pr/x86*:
- Adopted CK_CC_IMM macro.
- Dropped redundant constraints.
This work was mostly completed by Theo Schlossnagle
<jesus@omniti.com>, much thanks to him. He has
also provided access to a machine with Sun Studio 12.

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.
