arm/ck_pr: Make sure 64bits load/store are atomic.
...
Depending on the CPU implementation, ldrd/strd may or may not be atomic.
Use ldrexd/strexd instead.

ck_pr: (Re-)introduce ck_pr_rfo.
...
This was accidentally grouped into previous commit.
The destiny of this interface for internal use is still unclear (in context of
utilization in built-in data structures). The interface is enabled by default
on x86, as it is compatible with read-side prefetch* operations and
binary-compatible with 3DNow! extension. Older compilers will waste an
additional byte (they generate 3DNow! variant) on this, but older compilers
waste more on spillage if we encode instruction. Power support is coming soon.

This avoids memory traffic in busy-wait loops. Been on TODO list for a while,
may as well bite the bullet. No regressions introduced in recent versions of

ck_pr: Prettify the arm bits.
...
gcc is smart enough to use an even register for 64bits operations, and provide
a way to access the first and the second words, so use that instead of
hardcoding registers.
