[libbacktrace] Reduce memory usage in build_address_map

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.

[libbacktrace] Simplify memory management in build_address_map

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.

[libbacktrace] Fix memory leak in loop in build_address_map

When failing in build_address_map, we free the unit that's currently being
handled in the loop, but the ones that already have been allocated are leaked.

Fix this by keeping track of allocated units in a vector, and releasing them
upon failure.

Also, now that we have a vector of allocated units, move the freeing upon
failure of the abbrevs associated with each unit to build_address_map, and
remove the now redundant call to free_unit_addrs_vector.

Fix PR67974 for Darwin by adding an asm shim for AVX.

The PR is about a set of tests that were not executed because of
missing asm support.

However, the assembler can handle the insns now, so the tests are
attempted (but with a missing asm shim they fail).

This adds the shim.

In principle (bugs notwithstanding) Darwin’s x86_64 ABI is supposed
to follow the sysv psABI so we can have essentially a copy of the
Linux one.

the GCC configury was not detecting this because it was
