It seems that after adding the SP alignment to datalayout recently, I now see an error on my machine with compiler-rt tests: Profile-s390x :: instrprof-gc-sections.c. If I revert the change, the error goes away.
I am a bit new to using lld and even though I have not enabled it as a project with cmake, it seems to get built, which I didn't expect. I suppose it must be built for compiler-rt automatically somehow.
Any idea where the datalayout string lld is using could be fixed? @nikic @uweigand
```
/bin/clang -fuse-ld=lld -flto -o ./instrprof-gc-sections.c.tmp.lto /home/ijonpan/llvm-project/compiler-rt/test/profile/instrprof-gc-sections.c

PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
