BUILD: tree-wide: mark a few numeric constants as explicitly long long

Browse Source 
At a few places in the code the switch/case ond flags are tested against
64-bit constants without explicitly being marked as long long. Some
32-bit compilers complain that the constant is too large for a long, and
other likely always use long long there. Better fix that as it's uncertain
what others which do not complain do. It may be backported to avoid doubts
on uncommon platforms if needed, as it touches very few areas.
