[PATCH 0/6] aarch64 gas: memory management improvements

[Alice Carlotti]

These series is prompted by Matthieu's earlier patch series [1], and is an
alternative to his patches 1/4 and 4/4.

Patches 1-3 are a trivial cleanup, a bug fix and a documentation fix.  I think
these are ok to merge as they are, but I'll wait to see if there are other
opinions first.

Patches 4-6 eliminate most of the LeakSanitizer content for AArch64 GAS, but
are unnecessary outside that context, and startup/exit performance by around
10%.  These could be gated behind Alan's new BFD_ASAN macro [2].
