I was looking at these some more, and as it turns out we already have some
code to handle printing 64bit values.  HOST_WIDE_INT_PRINT_{DEC,UNSIGNED,HEX}
are format strings defined in machmode.h.

Seems to me the right way is to use those format strings to deal with
this problem instead of checking for this case in each of those files.

Can either you or JJ take care of this so that we can get these patches
installed?
