[llvm] [OCaml][test] Use correct data layout string. (PR #68781)

[Harald van Dijk via llvm-commits]

https://github.com/hvdijk created https://github.com/llvm/llvm-project/pull/68781

core.ml would previously set a data layout string of "e" and check that it remained "e". This is fragile when we have the data layout string auto-upgrade facility, and indeed broke when D86310 upgraded this one. As the auto-upgrade logic is not what is being tested here, it seems easier to just use the data layout string that the target expects.

Subject: [PATCH] [OCaml][test] Use correct data layout string.

core.ml would previously set a data layout string of "e" and check that
it remained "e". This is fragile when we have the data layout string
auto-upgrade facility, and indeed broke when D86310 upgraded this one.
As the auto-upgrade logic is not what is being tested here, it seems
easier to just use the data layout string that the target expects.
