Narrow down scope of the unknowns bitmap so that it is only accessible

gcc/ChangeLog:
* tree-object-size.cc (object_size_info): Remove UNKNOWNS.
Drop all references to it.
(object_sizes_set): Move unknowns propagation code to...
(gimplify_size_expressions): ... here. Also free reexamine
bitmap.
(propagate_unknowns): New parameter UNKNOWNS. Update callers.

This is a follow-up cleanup to pr#113012, but not required to fix that
bug. Bootstrapped on x86_64 and with config=ubsan.
OK, assuming it also went through a regression test or does so before
committing.
Thanks, yes, I also compared test results during the x86_64 bootstrap,
likewise for i686 after I had posted this.
