cppSplitBlocks :: ByteString -> [CodeBlock]

Break a Haskell code string into chunks, using CPP as a delimiter. Lines that start with '#if', '#end', or '#else' are their own chunks, and also act as chunk separators. For example, the code

#ifdef X
x = X
y = Y
#else
x = Y
y = X
#endif

will become five blocks, one for each CPP line and one for each pair of declarations.
