libFLAC/fixed.c: Fix undefined behaviour Left shift if a negative integer such that the sign bit is affected is (according to the C spec) undefined behaviour and the residual calculations using the shift operator were hitting this. Fortunately these same calculations using plain multiplication do not invoke UB and according to benchmarking (on x86_64 linux) have the same performance as the bit shift version.
