ARM NEON optimization -- celt_fir()
Hi all,
This is Linfeng Zhang from Google. I'll work on ARM NEON optimization in the
next few months.
I'm submitting 2 patches in the following couple of emails, which have the new
created celt_fir_neon().
I revised celt_fir_c() to not pass in argument "mem" in Patch 1. If there are
concerns to this change, please let me know.
Many thanks to your comments.

Several patches of ARM NEON optimization
I rebased my previous 3 patches to the current master with minor changes.
Patches 1 to 3 replace all my previous submitted patches.
Patches 4 and 5 are new.
Thanks,
Linfeng Zhang
