This is adding ulps for non-to-nearest tests on some architectures that
only support round-to-nearest and so have no such ulps in their existing
files.
(I am generically dubious of such an update not based on actually running
tests on the architectures involved - there can be architecture variations
because of differences in e.g. whether multiply and add get fused - but
adding ulps for tests that would not run on those architectures is
definitely wrong.)
