    A clang/test/Sema/global-explicit-register-undefined-type.c

  Log Message:
  -----------
  [clang][Sema] Crash due to asm labeled incomplete global register decls (#219746)

CheckAsmLabel fails to check for an incomplete type before attempting to
get the type layout. Short circuit on an incomplete type as Sema will
already reject a global with an incomplete type.
