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.
