953acd56a4 enc_neon: enable QuantizeBlock for aarch64 
vtbl4_u8 is available everywhere except iOS arm64: use vtbl2q_u8 there
with a corresponding change in the load.

2523aa73cb SmartRGBYUV: fix odd-width problem with pixel replication 
rightmost pixel was missing a copy, which could lead to invalid read.

Also added a lower dimension of 4, below which we use the regular conversion.
This is to prevent corner cases, in addition to not being overkill.

3fca851a20 cpu: check for _MSC_VER before using msvc inline asm 
_M_IX86 will be defined in mingw builds after including windows.h. as
the gcc inline asm is first, this missing check would only have caused
an error if the code was reorganized.

e2a83d7109 faster RGB->YUV conversion function (~7% speedup) 
with a special case for dithering==0., it gets somewhat faster on x86
thanks to inlining.

Also, less macros.

skal
3fc4c539aa Add smart RGB->YUV conversion option -pre 4 
New function: WebPPictureSmartARGBToYUVA()
This implement smart RGB->YUV conversion.

This is rather undocumented for now, and is triggered using '-pre 4'
preprocessing option.

This is slow-ish and use quite some memory, but should be improvable.
This is somehow a usable beta version.
