Cherry Mui	4ffa2aecc1	cmd/internal/obj/wasm: correct return PC for frameless wasmexport wrappers ... For a wasmexport wrapper, we generate a call to the actual exported Go function, and use the wrapper function's PC 1 as the (fake) return address. This address is not used for returning, which is handled by the Wasm call stack. It is used for stack unwinding, and PC 1 makes it past the prologue and therefore has the right SP delta. But if the function has no arguments and results, the wrapper is frameless, with no prologue, and PC 1 doesn't exist. This causes the unwinder to fail. In this case, we put PC 0, which also has the correct SP delta (0). Fixes #69584.
