c94e4bb103 Optimizes encoder NaN detection and clipping by only running them when needed 
NaN detection should now be able to catch values that would create NaNs
further down.

c16a96b458 Minor speedups to celt_pitch_xcorr_edsp(). 
This moves some stuff out of the main loop for the unaligned case.

a1740d9ad1 Drop the use of --always to git-describe 
This is a partial revert of c435f06b30,
since it didn't actually fix the original problem with shallow clones.
It returns just a hash, not something we (currently) can extract as a
version string in the form things are expecting.

e98816e9c1 Actually use my NEON code. 
I'd commented out mine and stuck azanelli's code in for testing,
 and then accidentally committed it like that.

5c02c5ffb5 Make celt_pitch_xcorr_edsp() work on ARMv5TE. 
We were assuming that LDR, LDRD, and STRD could be used on
 unaligned addresses, but this turns out not to be true on really
 old hardware.

aa8ff201b5 Clean up celt_pitch_xcorr() test code. 
This will be removed shortly, but at least it should be correct
 before it goes.
Makes the code get used unconditionally (when uncommented), and
 actually frees the buffer it allocates (now using the libopus
 allocation functions).

2924af4db0 Merges surround and stereo intensity stereo thresholds again.

93e1096093 Makes SILK surround masking a bit more aggressive in both directions

a47d6f308f Intensity stereo update, partially based on Monty's listening 
Intensity stereo is now based on equiv_rate and should no longer oscillate
in hybrid mode. Also, there is now a separate set of thresholds for
surround tuned by Monty. The non-surround thresholds were also updated at
low bitrate to be closer to what Monty found for surround.

135d1c9848 More make dist fixes 
Don't include the generated celt/arm/celt_pitch_xcorr_arm-gnu.S in the
dist tarball, but do include its celt_pitch_xcorr_arm.s source file.

d5cb06305b Fix 'make distclean'. 
Automake's dependency tracking seems to be confused by our asm
generation double-indirection. It's sufficient to have just
CLEANFILES = $(CELT_AM_SOURCES_ARM_ASM:.s.in=-gnu.S)
to fix the error about 'armopts-gnu.S' not being cleaned, but
celt_pitch_xcorr_arm-gnu.S is also not cleaned without raising
a warning. Therefore we explicitly clean both sets of ARM_ASM.
