…i16 and _mm256_mulhi_epu16 without LLVM intrinsics" This reverts commit 7abc64d599fcc93719f17ee08a03390d81424800.
Miri reports UB on division by zero with the LSX vdiv/vmod intrinsics when implemented via the portable simd_div/simd_rem helpers. [^1] Per clarification from the LoongArch ISA developers, the hardware defines that vdiv/vmod return 0 when the divisor is zero (this will be documented in the SIMD reference). This differs from the earlier assumption in PR rust-lang#2078, so the portable helpers are not a correct match. Switch back to the corresponding LLVM intrinsics so the Rust wrappers preserve the defined ISA behavior. [^1]: rust-lang/stdarch#2221 (comment)

Add libs-nominated triagebot config
The add expectation reads add.rn.f16x22, which is no PTX instruction. LLVM's own NVPTX codegen test, llvm/test/CodeGen/NVPTX/f16x2-instructions.ll, expects add.rn.f16x2 for fadd <2 x half>, and the sub, mul, fma and neg expectations in this file already match what it emits. Nothing caught the typo because assert_instr never runs on nvptx: CI builds that target with NORUN=1 and NOSTD=1. The neg docs name __hmin2 and the fma docs name __fma2 and __fma2_rn. cuda_fp16.h (CUDA 12.4) declares __hneg2 and __hfma2, and none of the other three names exist; the fma link already resolved to __hfma2.
