x86_64: enable struct field reordering
682690b 
The blocker for enabling this feature was my need to debug the emitted
assembly without debug info and having to manually inspect memory to
determine struct contents.  However, we now have debug info!

    (lldb) v -L foo bar
    0x00007fffffffda20: (repro.repro.Foo) foo = {
    0x00007fffffffda24:   .x = 12
    0x00007fffffffda20:   .y = 34
    }
    0x00007fffffffda28: (repro.repro.Bar) bar = {
    0x00007fffffffda28:   .x = 56
    0x00007fffffffda2c:   .y = 78
    }
