Hi Ben,

The following patch alters the ar cache representation from a singly linked list to a
hash table using the hashtab implementation from libiberty.  When archiving files
with thousands of archive members (eg. libjava), this patch results in a 15-25%
performance improvement.

Tested with an --enable-targets=all build, make check-binutils and a byte-wise
comparison of the libjava libraries built with and without a patched ar.

Okay to commit?

[Tut tut - no ChangeLog entry...]

Approved for the mainline, but not the 2.16 branch.

Cheers
  Nick
