Auto merge of #78809 - vn-ki:fix-issue-76064, r=oli-obk

add error_occured field to ConstQualifs,

fix #76064

I wasn't sure what `in_return_place` actually did and not sure why it returns `ConstQualifs` while it's sibling functions return `bool`. So I tried to make as minimal changes to the structure as possible. Please point out whether I have to refactor it or not.
