These data types...

..., and these uses...

..., and these tree dump scanning directives don't match up: a lot of
FAILs for anything that doesn't use 64-bit pointers, such as x86_64
GNU/Linux's '-m32' multilib.  This will need further tweaking to enable
tree dump scanning for all configurations, but for now, see attached
"Restrict 'c-c++-common/goacc/mdc-1.c' to LP64, LLP64"; committed to
trunk in r279720.
