The new option -di treats deprecation errors as informational warnings,
just like -wi show warnings as informational messages without triggering
Tests that required -d are updated to use -di options too to ensure -d
and -di works exactly the same (except for the compiler messages). Test
that didn't really required -d to run (usually obscure bugs only
triggered with -d), are now using both -d and -di as PERMUTE_ARGS
instead of REQUIRED_ARGS, so the are more generally tested.
