[libbacktrace] Reduce memory usage in build_address_map · eb33bf0a

In build_address_map we allocate a unit, and then look for addresses in the
unit, which we store in the addrs vector, with the elements pointing to the
unit.  However, if we cannot find addresses in the unit, the allocated unit is
not used.

Fix this by detecting if the allocated unit has been used, and reusing it
otherwise.

Bootstrapped and reg-tested on x86_64.

[libbacktrace] Simplify memory management in build_address_map · d9aa0961

In the main loop in build_address_map, we first read the abbrevs into a local
variable abbrevs, and then allocate the corresponding unit, after which we assign
the abbrevs to the unit.  This results in dedicated free-upon-failure
handling for the variable, and extra code to make sure that free-upon-failure
doesn't trigger once the unit has taken ownership of the abbrevs.

Simplify this by reversing the order of abbrev reading and unit allocation,
and eliminating the abbrevs local variable.

Bootstrapped and reg-tested on x86_64.
