Now that CompilerType uses a "TypeSystem *" and a "void *" instead of a "clang::ASTContext *" and a "void *", we need to know if anyone is trying to create a CompilerType from a clang::ASTContext that has no backing ClangASTContext.

This assert will fire if this is the case and we will need to fix the offending code.
