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.

Was LibYUVColorTest.TestFullYUV (896 ms)
Now LibYUVColorTest.TestFullYUV (212 ms)

80e27fc747 Add MaskCpuFlags(benchmark_cpu_info_) to unittest initialization
When command line --libyuv_cpu_info is used the individual tests
used to need to set the cpumask.  This CL moves that to the init
for each test class so the individual tests dont need to set it.

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.

7bffe5e1c5 lint warning fixes for CpuID
The CpuId function is a wrapper for the intrinsic, or
implemented with inline if unavailable.  It had been
using uint32, but the intrinsics use int, so it was causing
casting and lint warnings.  This change makes the internal
implementation use int.

Casting was also done for xgetbv, and the cast is simply
removed, and is not causing a build error.

MipCpuCaps was doing strlen to check for white space after the
instruction set.  Arm also does this but with a hard coded offset.
This was causing a cast from size_t to int, which produced a lint
warning.  The change removes the white space detect.
In theory the code could be used to detect SSE vs SSE2, and it would
need to check SSE is followed by a space or end of line.  But this
code is only used on Arm and Mips, where there there is one form
of SIMD detected.  e.g. MSA for mips.  If a new instruction set is
added with a similar name, the write space check could be reintroduced.
But its more likely the code can be rewritten to use a better form
of detection by then. Or remove detection and require the instructions

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.
