I have checked this conversion is not needed anymore after the previous commit, by running various smoke tests of which none triggered this optimization. The only case where the optimization would have kicked in is in syscall/syscall_windows.go:76 of the Go standard library. Therefore, I prefer to remove it to reduce code complexity.
