From: Andi Kleen <ak@odo.jf.intel.com>

With the recent tuning the C version of rwlocks is basically the same
performance as the x86 assembler version for uncontended locks (with a
a few cycles near the run-to-run variability). For others it should not
matter anyways.

So remove the assembler code and use the C version like other
architectures.

I was referring to either the benchmark I wrote or the one that Ondrej
wrote, since my concern was to get a benchmark into glibc.  If you can
either validate using either of the benchmarks or confirm that your
benchmark has the same characteristics (which it seems to based on
your description) then we can include the microbenchmark for it.
