description:
update to polyml-5.9.2-2 version ccd3e3717f72 from branch fixes-5.9.2, which 
provides a corrected implementation of IntInf right shift;
keep redundant checks for further testing;


The plan is to publish it in Isabelle2025-1-RC4 next week (probably Monday), 
and remove the redundant check for the final release.

The changeset will return to isabelle-dev shortly after Isabelle2025-1-RC4.
