Feature/serialization debug info (#767)

* Remove AppContext. Use StdChannels to hold writers, and TestToolUtil to hold test tool specific functionality.

* StdChannels -> StdWriters

* getStdOut -> getOut, getStdError -> getError

* Renamed main.cpp files of tools to try and stop visual studio getting confused between files - such that clicking on an error takes editor to the right location.

* Work in progress on being able to serialize debug information.

* * Added MemoryStream
* First pass converting to IRSerialData
* Able to read and write IRSerialData with debug data

* Start at reconstruting IR serialized data.

* First pass of generation debug SourceLocs from debug data. Works for test set for line nos.

* Bug fixes.
Moved testing of serialization into IRSerialUtil

* Work around problem with  irModule = generateIRForTranslationUnit(translationUnit); two times in a row produces different output(!). Fix by just creating once.

* Remove problem with use of ternary op in slang.cpp on gcc/clang.

* Added -verify-debug-serial-ir option that makes IR modules go through full serialization with debug information and verification.

* Add a test that does serial debug verification that is run by default on linux.
