PR 61084: Use widest_int in sparc_fold_builtin

[Richard Sandiford]

This is the second part of PR 61084, which it seems I'd forgotten to post.
pdist calculates a wide result from narrower inputs, so I should have
used widest_int rather than wide_int.

Tested by Rainer on SPARC Solaris.  OK to install?

Thanks,
Richard
