Revert "Add some regression test cases for denormalized float8 input."
This reverts commit500cf66. As wasmore or less expected, a small minority of platforms won't acceptdenormalized input even with the recent changes. It doesn't seemespecially helpful to test this if we're going to have to provide analternate expected-file to allow failure.
