  3. Fix scala-native#626: Do not use fixed sized ByteBuffers in CodeGen 

    The buffers provided by withScratchBuffer has a fixed size which for
large programs might be insufficient. Since CodeGen internally uses a
StringBuffer we can instead allocate a buffer of the suitable size.

  4. Fix scala-native#580: Make ByteBufferPool less memory-hungry 

    Reduce the buffer size to 8M based on the fact that the largest .nir file
currently in the repo is java.lang.Character at ~2M:

    > find . -name "*.nir" | xargs stat -f "%z %N" | sort -n | tail -5
