Title: Multiple source files per sourcemap

This adds support for multiple sources in the source map output.

In what I believe is a backwards-compatible change, setting `options.sourceMap` to `true` causes the generated source map to use `loc.source` for the source file (conforming to the Parser APi spec for `SourceLocation`).
