Because `wasmMaxStackArgBytes` is calculated early on, it was possible we later eliminated all call instructions and `needsStaticStackAlignment` was false, but we still included `wasmMaxStackArgBytes` in the frame size, breaking stack alignment invariants on ARM64. The simplest fix is to not include `wasmMaxStackArgBytes` if we know there are no calls (left). This fixes an old Ion ARM64 bug exposed by the assertion added in bug 1774449.
