PCH: fix a regression that reports a module is defined in both pch and pcm. In r276159, we started to say that a module X is defined in a pch if we specify -fmodule-name when building the pch. This caused a regression that reports module X is defined in both pch and pcm if we generate the pch with -fmodule-name=X and then in a separate clang invocation, we include the pch and also import X.pcm. This patch adds an option CompilingPCH similar to CompilingModule. When we use -fmodule-name=X while building a pch, modular headers in X will be textually included and the compiler knows that we are not building module X, so we don't put module X in SUBMODULE_DEFINITION of the pch.
