Summary: Macro like `va_start`/`va_end` marked as builtin functions that makes these identifiers special and it results in redefinition of the identifiers as builtins and it hides macro definitions during preloading C++ modules. In case of modules Clang ignores special identifiers but `PP.getCurrentModule()` was not set. This diff fixes IsModule detection logic for this particular case.
