[PATCH 0/4] RFC: port gas to use libiberty htab hash table

[Martin Liska]

Motivation of the change is mentioned in PR gas/26381 where gas is right
now using a fixed sized hash tables. That brings problems for large application
with LTO where one assembled .s file can be ~100MB big.

This patch set is first part of transition where I would like to hear a feadback
from community. I'm planning to carry on and migrate all hash tables in gas
so that gas/hash.[ch] can be removed.

I tested my patches on x86_64-linux-gnu and I also build and tested iq2000
cross binutils.

Thoughts?
Thanks,
Martin
