>+        [WHLSL] Add the statement behavior checker

>+        Reviewed by NOBODY (OOPS!).
>+
>+        This is a translation of https://github.com/gpuweb/WHLSL/blob/master/Spec/source/index.rst#typing-statements
>+        into C++. It is meant to replace the ReturnChecker and UnreachableCodeChecker in the reference implementation.
>+
>+        No new tests because it isn't hooked up yet. Not enough of the compiler exists to have any meaningful sort
>+        of test. When enough of the compiler is present, I'll port the reference implementation's test suite.

>+        * Modules/webgpu/WHLSL/WHLSLStatementBehaviorChecker.cpp: Added.
