Do not call bremfree for managed buffers.

Calling bremfree for these buffers results in panic:
"bremfree: buffer %p not on a queue."

Forced commit to denote that the claim in r235388, that libcompiler_rt when
used as a replacement for libgcc on sparc64 would cause a 60% decrease in
performance is wrong. Actually, the performance loss is only marginal and
the huge difference seen was caused by a pilot error comparing libgcc builds
using MALLOC_PRODUCTION with libcompiler_rt builds that did not.

Switch sparc64 to using libcompiler_rt; since r230021 we have a workaround
in place allowing it to be used there and since r235388 (see also r235486)
we also have usable div/mod optimizations like libgcc has.

Migrate ath_debug and sc_debug from an int to a uint64_t / QUAD;
add some more BAR debugging logic.

* Change the definition of ath_debug and ath_softc.sc_debug  from
  int to uint64_t;
* Change the relevant sysctls;
* Add a new BAR TX debugging field;
* Use this in if_ath_tx.

This has been tested by using the sysctl program, which happily allows
for fields > 32 bits to be configured.
