added inputs giving large errors on x86_64 for new C23 functions

These functions are exp10m1, exp2m1, log10p1, log2p1.
Also regenerated ulps on x86_64.

For each format, there are 4 values, one for each rounding mode.
(For the intel96 format, there are 8 values, 4 for Intel hardware,
and 4 for AMD hardware. However, regen-ulps was only run on Intel.
It should be run in a separate patch on a AMD x86_64.)
