stub + basic cmake support for targeting native code generation using
portable intrinsics / wasm (WebAssembly). integrating this into the
webp_js path will be left until the implementation is more complete.

f209a5481e Use the plane code and not the distance when computing statistics. 
As backward references use the plane code when checking the cost
of a distance, statistics used to compute the cost should use it too.
This provides a small compression improvement at no speed cost.

Pascal Massimino
f8fad4fac1 lossless incremental decoding: fix missing eos_ test 
The patch  21735e0 introduced a bug where a goto path was not testing
the eos_ state.  If this happened just before a row_sync, a SaveState()
would be called that would store the eos_ state as '1' till the end
of the loop.  This usually was not a problem, except for the very last
chunk where we disable the incremental decoding altogether (we have all
the data). The termination tests were then going wrong.
The fix is to add a proper eos_ test and avoid falling in this inconsistent
state.
