[PATCH, committed] Add -ftree-tail-merge to tail-merge testcases

- Authentication-results: sourceware.org; auth=none
Hi,
this patch adds -ftree-tail-merge to tail-merge testcases.
There is no separate dump for tail-merge, instead the test-cases use
-fdump-tree-pre, so it's not easy to spot that they're tail-merge test-cases.
This patch fixes that by adding an explicit -ftree-tail-merge.
Committed as obvious.
Thanks,
- Tom
