Add SourceManager that can keep track of multiple source file syntax nodes along with their external representations. The source manager can emit diagnostics into any of those files, including tracking any explicitly "detached" syntax nodes used for macro expansion. Make sure we detach syntax nodes before passing them to macro implementations, so they cannot see more of the source file than they are permitted. We hadn't been doing this before (by accident), and doing so motivated the introduction of the SourceManager. Additionally, perform operator folding on macro arguments as part of detaching them. Macro clients shouldn't have to do this, and moreover, when clients do this, they lose the ability to easily emit diagnostics on the now-folded nodes.
