Dan Gohman 2f16f25391 [WebAssembly] Don't special-case call operand order.
With the '=' suffix now indicating which operands are output operands, it's
no longer as important to distinguish between a call's inputs and its outputs
using operand ordering, so we can go back to printing them in the normal order.
