Avoid skipping an initializer with a goto

C++ doesn't allow skipping initialization with a goto. This means that
this code is illegal:

  void func(bool b) {
    if(b) goto END;
    int value = 0; //error C2362 with /permissive-
    //... value used here
  END:
    return;
  }

Adding an extra scope makes the code legal. This problem is only
detected with /permissive- but now that compiling with this
switch is practical we might as well stay /permissive- clean:

Note that compiling /permissive- clean only works with the 10.0.16299.0
SDK which currently has other issues...
