cmd/compile/internal/gc: fix return value offset for SSA backend on ARM

Progress on SSA backend for ARM. Still not complete. It compiles a Fibonacci function, but the caller picked the return value from an incorrect offset. This CL adjusts it to match the stack frame layout for architectures with link register. Updates #15365.
