Compat: Fixes for format reinterpretation

format reinterpretation is not supported in compat mode.
The format_reinterpretation tests already filter out every
case where format == viewFormat so all that's left is cases
that don't work in compat.

The createView tests test multiple combinations, some of which
are valid and some are not.
