  -----------
  [ARM] Enable MVE masked loads and stores

With the extra optimisations we have done, these should now be fine to
enable by default. Which is what this patch does.

  Log Message:
  -----------
  [CommandLine] Add missing Callbacks

It appears that the cl::bits options are not used anywhere in-tree. In
the recent addition to add Callback's to the options, the Callback was
missing from this one. This fixes it by adding the same code from the
other classes.

It also adds a simple test, of sorts, just to make sure these continue
compiling.
