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.
