tree-optimization/103456 - Record only successes from object_sizes_set
Avoid overwriting osi->changed if object_sizes_set does not update the
size, so that a previous success in the same pass is not overwritten.
This fixes the bootstrap-ubsan build config, which was failing due to
incorrect object size.
gcc/ChangeLog:
PR tree-optimization/103456
* tree-object-size.c (merge_object_sizes): Update osi->changed
only if object_sizes_set succeeded.
gcc/testsuite/ChangeLog:
PR tree-optimization/103456
* gcc.dg/ubsan/pr103456.c: New test.
