Log Message:
lint: don't rely on the floating point rounding mode

When checking whether a floating point constant can be converted to an
integer constant with the same value, ULLONG_MAX is not representable
exactly in a 64-bit long double, so the comparison value could have been
rounded down, leading to wrong warnings about lossy conversions.

Perform exact calculations instead.
