Issue Description:

When you type:

$ xcrun swift-demangle
< input1
< input2
< Ctrl+D
> output1
> output2

You don’t get any output until you Ctrl+D to close the stream. Could we make swift-demangle incremental line by line (or \0 by \0 if needed)? I.e.:

$ xcrun swift-demangle
< input1
> output1
< input2
> output2
< Ctrl+D

This would have general memory usage and performance goodness for piped code.
