Add bad-reg inline assembly ui test for RISC-V and s390x https://github.com/rust-lang/rust/pull/131341#discussion_r1826555431 > Btw, such unsupported registers are present in most architectures, but only aarch64/arm64ec, x86_64, and not yet merged [sparc/sparc64](https://github.com/rust-lang/rust/pull/132472/files#diff-02aebda3376c2b020265137f9ce2c387669ca5cfecd7d60494275c2387db5114) (and powerpc/powerpc64 by this PR) currently have ui tests for them. I plan to add tests for other arches later. Starting with RISC-V and s390x, which I'm familiar with and relatively easy to check for correctness. (Relevant rustc code are supported_types/def_regs/overlapping_regs in [compiler/rustc_target/src/asm/riscv.rs](588a420350/compiler/rustc_target/src/asm/riscv.rs) and [compiler/rustc_target/src/asm/s390x.rs](588a420350/compiler/rustc_target/src/asm/s390x.rs).) r? workingjubilee `@rustbot` label +A-inline-assembly
