   switch statements must not jump into the scope of VM declarations.

   c99-vla-jump-2.c tests with many other labels and gotos, VLAs.
   c99-vla-jump-3.c tests with just that label and goto, VM.
   c99-vla-jump-4.c tests with many other labels and gotos, VM.
   c99-vla-jump-5.c tests with switch statements.  */
