Subject: WIP: slang to C++ code generation (#997)

* WIP: Emitting Cpp

* Added HLSLType instead of using IRInst - because they don't seem to be deduped.

* Removed need for lexer to take a String.
Added mechansim to lookup intrinsic functions on C++.

* A c/c++ cross compilation test.

* WIP Cpp output using cloning and slang types.

* More work to generate mul funcs.

* WIP: Outputting some simple C++.

* Expose findOrEmitHoistableInst to IRBuilder to aid cloning,

* Simplification for checking for BasicTypes.
Test infrastructure compiles output C++ code.

* Dot and mat/vec multiplication output.

* First pass at swizzling.

* First support for binary ops.

* Builtin binary and unary functions.

* Any and all.

* WIP adding support for other functions.
Added code to generate function signature.

* Add scalar functions to slang-cpp-prelude.h

* Support for most built in operations.

* Tested first ternary.

* Checking the emitting of corner cases functions - normalize, length, any, all, normalize, reflect.

* Check asfloat etc work.

* Fmod support.

* WIP Array handling in C++.

* First stage in being able to handl arbitrary type output for CLikeSourceEmitter

* Removed Handler/Emitter split - so can implement more easily complex type naming.

* Array passing by value first pass.

* Rename Array -> FixedArray

* Outputs structs in C++.

* Emit the thread config.

* Dimension -> TypeDimension

* SpecializedOperation -> SpecializedIntrinsic
Operation -> IntrinsicOp
Use shared impl of isNominalOp
Commented use of m_uniqueModule etc.

* Add code to test slang->cpp when compiled doesn't have errors. Does so by building shared library and exporting the entry point.

* Fix linux clang/gcc compile error about override not being specified.

* Make sure c-cross-compile is run on linux targets/smoke.

* Remove c-cross-compile.slang from smoke.

* Fix running tests/cross-compile/c-cross-compile.slang on Ubuntu 16.04

* Only add -std=c++11 for C++ source.
