bb966ca835 Optimized function WebRtcSpl_ScaleAndAddVectorsWithRound() for ARM-NEON platforms, and refactor it for generic C. 
We removed it out of ilbc_specific_functions.c, since it's used not only in iLBC.

Passed the unit test.

bfa7f96d1e Optimized WebRtcSpl_ComplexBitReverse() for general ARM platforms and generic C. 
In ARMv5, the cycles were reduced by 88% (weight in VoE reduced from 3.554% to 0.432%). The tradeoff is a memory increase of 704 bytes.

59f16ec993 Introduced ARM version of WebRtcSpl_SqrtFloor(). Function cycles reduced by ~ 30% in a real time VOE test in an android device (Nexus-S, ARMv7a). 
// Fritz, I added you as a reviewer for the assembly files, just as a warm-up for future storms. :-) The assembly code was from public domain and there's little to touch.

4bc24c4afa Optimized function WebRtcSpl_FilterARFastQ12 for ARM platform. 
Speed close to doubled for an offline test in NetEq.
Bit exact.

b0abbd353d Optimized spl function WebRtcSpl_CrossCorrelation for ARM Neon platforms. 
When used in Neteq, Neteq performance improved from 13 to 33% with different
test configurations.
Output is not bit-exact with generic C code in file cross_correlation.c, 
due to reduction of shift operations from using Neon registers, although in
theory now the result is more accurate than before.

132feb1270 Made tables static. 
In this CL global tables have been moved to where they are actually used. If for some reason they need to be available in a larger scope we can add them again at that point.
