efbf15754a Step thru full color test by increments of 5 for better test speed.
Full color test is the slowest of the unittests, and not catching any
additional bugs at the moment.  Step thru range of 0 to 255 in steps of
5 to speed up the test.  255 is 3 * 5 * 17, so any of those primes would
hit 0 and 255 exactly.

f0a9d6d206 Gaussian reorder for benefit of A73
Roughly. instead of 4 loads and 8 multiples, use 1 load and 2 multiples
4 times over.  The original code, as with the C code from clang and gcc,
did all the loads, then all the math, then the store.  The new code
does a load, then the math, then the next load, etc.
This schedules better on current arm 64 cpus.
Number of registers also reduced, reusing the same registers.

f553db2d30 HalfFloatPlane unittest for denormal half floats
Halffloats have a limited range.  It shouldnt normally come up, but if the scale value passed in produces a small value, the half floats will be denormals, which are slow and/or flust to zero.  This test ensures they behave the same in C and SIMD and tests the performance of denormals.

d363ea6527 Remove I411 support.
YUV 411 is very uncommon format.  Remove support.

Update documentation to reflect that 411 is deprecated.

Simplify tests for YUV to only test with the new side by side YUV but keep old 3 plane test around with a macro for now.

width %w size modifier the int width can be passed directly to arm assembly.
For functions that take input constants, the outputs are declared as early
write using &, meaning the outputs use used before all inputs are consumed.

ifdefs on a function level are not needed for neon functions, unless
they are conditionally enabled in row.h.  No functions are conditionally
enabled at this time, so all ifdefs can be removed from row_neon.cc and
