 Pass -z <arg> to the linker

----------------
extraneous change?

+TARGET_BUILTIN(__builtin_wasm_qfms_f32x4, "V4fV4fV4fV4f", "nc", "simd128")
----------------
is QFMA actually in MVP simd? I thought it was non-deterministic?

-  } else if (NumConstantLanes >= NumSplatLanes &&
-             Subtarget->hasUnimplementedSIMD128()) {
-    // If we support v128.const, emit it directly
+  } else if (NumConstantLanes >= NumSplatLanes) {
     SmallVector<SDValue, 16> ConstLanes;
----------------
out of curiosity, are there any cases where a splat could be smaller than a v128 const, since the consts are pretty big?
