Parsing CPP Compiler output (#994)

* Added extractLine line parsing to StringUtil. Use for matching lines instead of calcLines. calcLines uses extractLine to extract lines.
Fixed problems found in output of some tests- due to how a how final line is handled. Now a final line has a \r or \n\r combination, but nothing else after it, it is considered the last line (not the line after it).

* Use StringUtil::extractLine in slang-generate.

* Improved comment on extractLine

* Remove test code from StringUtil::extractLine

* Made StringUtil::extractLine act as if line terminators are 'separators'.
Added unit-test-string.cpp - to check behavior.

* Adding LineParser - not entirely necessary, but slightly easier to use.

* Hack to output start of tests.

* WIP parsing CPPCompiler output.

* Make extractLine return a bool.

* First attempt at Visual Studio output parsing.

* Add handling for checking error returning from CPPCompiler.

* First pass parsing output of Gcc/Clang.

* Split out VisualStudioCompilerUtil and GCCCompilerUtil.
Simplified parsing of versions.

* Simplify CPPCompiler::Output interface.

* Fix problem with cpp-compiler on linux targets.

* Add shared library link error.

* Improving GCC/Clang parsing output.

* Make cpp compiler parsing function able to return a SlangResult.

* Handling for 'info' on clang

* Add expected result for c-compile-shared-library-error.c

* * Add flags such that link errors on shared libraries are supported.
* Added StringUtil::join

* Turn off the link shared library unfound symbol option on MacOS because it causes an error (and it's not needed on that target).

* Add natvis inclusion back to visual studio projects.

* Display message to try and determine crash problem on travisbuild.

* Fix bug in handling continuations for clang.
Disabled output of exception text.

* WIP: See what clang is outputting that is parsing incorrectly on travis.

* More handling for travis clang parsing issue.

* Restore natvis to core.vcxproj

* Fix visual studio project such that it still as natvis.
