Description
The WASM SIMD intrinsic std::arch::wasm32::u8x16_sub_sat used to be compiled to the WASM instruction i8x16.sub_sat_u. Since the switch LLVM 20 (bisected) it is compiled to call llvm.wasm.sub.sat.unsigned.v16i8
Other intrinsics (e.g. saturated integer addition) do not seem to be affected.
