Fixes #109627.
In order to ensure that function exits have a line number, the compiler duplicates small exit blocks which (1) do not have a line number in any instruction and (2) have more than one predecessor. Since these blocks are jump targets (at least one predecessor reaches this block via a jump or exception), they need to have labels assigned to them. This was missing, and is added in this PR.
