Fix PR target/63408

The attached patch fixes PR target/63408 and adds a regression test
for the same. The problem is essentially that
vfp3_const_double_for_fract_bits() needs to be aware that negative
values cannot be used in this context.

Tested with a bootstrap and regression test run on armhf. Applied.
