As described in the PR, wi::divmod_internal was sign- rather than
zero-extending a modulus result in cases where the result has fewer
HWIs than the precision and the upper bit of the upper HWI was set.
This patch tries to make things more robust by getting wi_pack
to handle the canonicalisation step itself.
Tested on x86_64-linux-gnu. I added tests to the wide-int
plugin since that seemed more direct.
