This is slightly more complicated than usual because there are many C
and assembler implementations of the spinlock functions.

Full consolidation in a single C implementation is not possible because
the algorithm is subtly different, and PTHREAD_SPINLOCK_INITIALIZER
varies.  I did not try to simplify this, but instead patched all the
different implementations.

Tested on i686-linux-gnu, powerpc64le-linux-gnu, x86_64-linux-gnu.
Built with build-many-glibcs.py, both with defaults and with binutils
2.33 and GCC 9.
