Subject: Source map obfuscation  (#2717)

* #include an absolute path didn't work - because paths were taken to always be relative.

* WIP source map.

* Split out handling of RttiTypeFuncs to a map type.

* Make RttiTypeFuncsMap hold default impls.

* Slightly more sophisticated RttiTypeFuncsMap

* Source map decoding.

* Fix tabs.

* Fix asserts due to negative values.

* Use less obscure mechanisms in SourceMap.

* Source map decoding.
Simplifying SourceMap usage.

* First attempt at ouputting a source map as part of emit.

* Added support for -source-map option. SourceMap is added to the artifact.

* Small improvements around column calculation in SourceWriter.

* Source Loc obuscation WIP.

* Fix some issues around SourceMap obfuscation.

* Split out obfuscation into its own file.

* Keep obfuscated SourceMap even through serialization bottleneck.
