ck_backoff: Remove usage of volatile.
...
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
GCC, clang and ICC.

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.

ck_swlock: We shouldn't decrement n_readers when
...
ck_swlock_read_latchlocks observers a writer if the unlatch
operation sets n_readers to 0.
The unlatch operation now just unsets the latch bit, we can safely
decrement n_readers in ck_swlock_read_latchlocks().
+ Fixes to validation tests & ELIDE coverage.

ck_bitmap: more bulk operations, less space, more tests
...
* new bulk rmw: intersection, intersection_negate (with complement),
* new bulk reads: empty, full, count, count_intersect
* ck_bitmap_iterator fixes: avoid out of bounds read on empty bitmaps,
and ck_bitmap_next is marginally faster on sparse bitmaps .
* less space: the bitmap itself is an array of unsigned int, which
eliminates alignment padding between the n_bit field and the bitmap.
* more unit tests.
