Subject: [OPENMP] Fix crash on code emitting if errors are found.

Codegen for threadprivate variables (and in some other cases) may cause crash of the compiler if some diagnostic is produced later. This happens because some of the autogenerated globals are not removed from InternalVars StringMap when llvm::Module is reset.
