Rollup merge of #127506 - liushuyu:s390x-target-features, r=davidtwco
rustc_target: add known safe s390x target features This pull request adds known safe target features for s390x (aka IBM Z systems). Currently, these features are unstable since stabilizing the target features requires submitting proposals. The `vector` feature was added in IBM Z13 (`arch11`), and this is a SIMD feature for the newer IBM Z systems. The `backchain` attribute is the IBM Z way of adding frame pointers like unwinding capabilities (the "frame-pointer" switch on IBM Z and IBM POWER platforms will add _emulated_ frame pointers to the binary, which profilers can't use for unwinding the stack). Both attributes can be applied at the LLVM module or function levels. However, the `backchain` attribute has to be enabled for all the functions in the call stack to get a successful unwind process.
