Update stdarch submodule and remove special handling in cranelift codegen for some AVX and SSE2 LLVM intrinsics rust-lang/stdarch#1463 reimplemented some x86 intrinsics to avoid using some x86-specific LLVM intrinsics: * Store unaligned (`_mm*_storeu_*`) use `<*mut _>::write_unaligned` instead of `llvm.x86.*.storeu.*`. * Shift by immediate (`_mm*_s{ll,rl,ra}i_epi*`) use `if` (srl, sll) or `min` (sra) to simulate the behaviour when the RHS is out of range. RHS is constant, so the `if`/`min` will be optimized away. This PR updates the stdarch submodule to pull these changes and removes special handling for those LLVM intrinsics from cranelift codegen. I left gcc codegen untouched because there are some autogenerated lists.
