Safety check: Don't directly abort.
...
The sized dealloc checks called the generic safety_check_fail, and then called
abort. This means the failure case isn't mockable, hence not testable. Fix it
in anticipation of a coming diff.

Prof: Add prof_unbias.
...
This gives more accurate attribution of bytes and counts to stack traces,
without introducing backwards incompatibilities in heap-profile parsing tools.
We track the ideal reported (to the end user) number of bytes more carefully
inside core jemalloc. When dumping heap profiles, insteading of outputting our
counts directly, we output counts that will cause parsing tools to give a result
close to the value we want.
We retain the old version as an opt setting, to let users who are tracking
values on a per-component basis to keep their metrics stable until they decide
to switch.
