5e7780d2d8 lz4frame : removed some intermediate stage from LZ4F_decompress() 
ensure some strange jump cases are not possible
(they were already not possible, but static analyzer couldn't understand it).

4d61ebc9c8 modified formulation for LZ4F_compressBound() 
previous version used an intentional overflow,
which is defined since it uses unsigned type,
but static analyzer complain about it.
