Dear Fortranners,

the use of -fdefault-integer-8 exhibits several cases where
we missed to convert the result of an intrinsic from the
declared to the effective resulting type.

The attached obvious patch fixes this for IMAGE_STATUS,
TEAM_NUMBER, and POPCNT/POPPAR.

OK for mainline if regtesting passes on x86_64-pc-linux-gnu?

Thanks,
Harald
