This may be a DUP of 106819. Does the patch in it solve this PR?

I tried dae8b9e2bbb6017bf90d68c7b720c500125c8295, r13-2390-gdae8b9e2bbb601 and
I am still seeing the failures.

Reproduced with an installed stage1 compiler and then doing:
PATH=/install/path:$PATH
LD_LIBRARY_PATH=/install/lib64
make clean-mpfr
make check-mpfr
But now it's been fixed by:

Do not clobber signbit when unioning a NAN.
When unioning a known NAN and something else, we're dropping the
properties of the NAN, particularly the sign. This fixes the
oversight.
With this patch, we should be keeping the sign bit up to date, even in
the presence of NANs.
gcc/ChangeLog:
* value-range.cc (frange::union_): Do not drop properties when
unioning a NAN with something else.
(range_tests_signed_zeros): Add tests.
