Subject: Simple test profiling (#1062)

* First pass support for performance profiling

* Test across all elements

* Fix bug - sourceContents is not used, should use rawSource.

* * Add ability to get prelude from API.
* Allow specifying source language for render-test
* Made it possible to compile a test input file as C++
  * Special handling for reflection
* Added C++ impl to performance-profile.slang

* Remove some clang warnings.

* Output profile timings on appveyor and other TC.

* Remove passing around of StdWriters (can use global).
Small comment improvements.
