The union idea sort of works, but it's clunky enough I'm not going to pursue it. The most verbose version:
```
    fpcr = 0x00000000
         = {
<...>
             RMode = (meaning = RN, value = 0)
```
Then you can set a decl printing helper and match on the generated type names to remove
some of it:
```
    fpcr = 0x00000000
         = {
<...>
             RMode = {
                RN
               RMode = 0
             }
```
With a typedef I could remove the final "RMode", right now it's "unsigned int:2" so the
helper doesn't kick in.

Seems to force vertical layout, and the two values will always be on separate lines.
This looks awkward enough that I'd rather just keep the existing format.

Now I'll see if I can use the existing dump code for all but the enums, as you suggested.
