Recent commits (2098ad7f00324ee0f2a6538f418a6f81dfdd2edb and
15a9a72ee68166c0cff3f036cacd3c82be66c729) replaced usage of "o.value()"
on optionals with "*o". Those optional values are expected to be
present -- but now, if it ever turns out that they're not,
compilation will proceed with garbage data rather than crashing
immediately (and more debuggably) with an uncaught exception.
Add asserts for presence to restore the previous level of safety.
(I could have revert these patches so as to resume used of .value()
but I didn't want to just have them get broken again.)

std::optional::value() has undesired exception checking semantics and is
unavailable in older Xcode (see _LIBCPP_AVAILABILITY_BAD_OPTIONAL_ACCESS). The
call sites block std::optional migration.
Flang C++ Style Guide tells us to use x.value() when no presence test
is obviously protecting the reference. Since assert can be disabled,
I don't count it as "protection" here.

system_clock intrinsic calls with dynamically optional arguments
Modify intrinsic system_clock calls to allow for an argument that is optional
or a disassociated pointer or an unallocated allocatable. A call with such an
argument is the same as a call that does not specify that argument.
Rename (genIsNotNull -> genIsNotNullAddr) and (genIsNull -> genIsNullAddr)
and add a use of genIsNotNullAddr.

This patch enables the lowering of the `sum` intrinsic. It adds
also infrastructure to deal with optional arguments in intrinsics and
implied loops.
