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.

	* dwarf.c (build_address_map): Reuse unused units.

From-SVN: r267445

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.

	* dwarf.c (build_address_map): Simplify by removing local variable
	abbrevs.

From-SVN: r267444

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.

Bootstrapped and reg-tested on x86_64.

While upon failure in build_address_map we call free_unit_addrs_vector, this
does not actually free the addrs vector, but merely the abbrevs of the units
pointed at by the elements of the addrs vector.

Fix this by adding code to build_address_map to make sure that the addrs vector
is freed upon failure.
