… instead of
stripping PackType out of diagnostic arguments.
There are places in the type printing code that assume the substitution for a
type parameter pack is always a pack, and violating that invariant will crash
the compiler. We also never want to print 'Pack{...}' in diagnostics anyway,
so the print option is a better approach and fixes a few existing tests that still
contained 'Pack{...}' in error messages.
