Rollup merge of #130558 - taiki-e:s390x-atomic-128, r=cuviper
Support 128-bit atomics on s390x Since LLVM 18 (https://github.com/llvm/llvm-project/commit/c568927f3e2e7d9804ea74ecbf11c16c014ddcbc), 128-bit atomics are fully supported on s390x. And the current minimum external LLVM version is now 18 (https://github.com/rust-lang/rust/pull/130487). s390x 128-bit atomic instructions (lpq,stpq,cdsg) has been present since [the First Edition of the Principles of Operation](https://publibfp.dhe.ibm.com/epubs/pdf/dz9zr000.pdf). (LLVM's minimal supported architecture level [is z10 (the Eighth Edition of the PoP)](https://github.com/llvm/llvm-project/blob/llvmorg-19.1.0/llvm/lib/Target/SystemZ/SystemZProcessors.td#L16-L17).) cc https://github.com/rust-lang/rust/issues/99069 r? `@cuviper`
