Catch overflow when rounding intervals in AdjustIntervalForTypmod.
Previously, an interval microseconds field close to INT64_MAX or
INT64_MIN could overflow, producing a result with not even the
correct sign, while being rounded to match a precision specification.
This seems worth fixing, but not worth back-patching, in part
because the ereturn() notation doesn't exist very far back.
Report and patch by Joseph Koshakow (some cosmetic mods by me)
