first realisation of splitting floating point compares
activated with AFL_LLVM_LAF_SPLIT_COMPARES=1 needs testing on big endian machines A compare is split into sign integer comparison exponent integer comparison mantissa/fraction integer comparison These integer comparisons are further splitted if they are bigger than a byte.
