  -----------
  [ctx_prof] Remove the dependency on the "name" GlobalVariable

We don't need that name variable for contextual instrumentation, we just
use the function to get its GUID which we pass to the runtime, and rely
on metadata to capture it through the various optimization passes. This
change removes the need for the name global variable.
