Hi,

after switching from LLVM 11 to LLVM 13 for postgresql-14's JIT
mechanism, JIT fails on s390x with

2021-12-03 11:07:38.194 UTC client backend[815426] pg_regress/tablespace ERROR:  failed to JIT module: Added modules have incompatible data layouts: E-m:e-i1:8:16-i8:8:16-i64:64-f128:64-a:8:16-n32:64 (module) vs E-m:e-i1:8:16-i8:8:16-i64:64-f128:64-v128:64-a:8:16-n32:64 (jit)

The other architectures are fine (armel/armhf fail for a gcc-11 ICE).
