[NFC][clang] Add ubsan-trap-merge.c test to show absence of nomerge (#117649)
This test (copied from https://github.com/llvm/llvm-project/pull/83470)
demonstrates that UBSan does not add the nomerge annotation. This is
significant because it can result in them being merged by the backend,
even when -ubsan-unique-traps is enabled.
N.B. https://github.com/llvm/llvm-project/pull/65972 (continuation of
https://reviews.llvm.org/D148654) had considered adding nomerge to
ubsantrap, but did not proceed with that because of
https://github.com/llvm/llvm-project/issues/53011.
https://github.com/llvm/llvm-project/pull/101549 fixed that limitation
("It sets nomerge flag for the node if the instruction has nomerge
arrtibute."); planned upcoming work
(https://github.com/llvm/llvm-project/pull/117651) will add nomerge for
ubsan.
