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.)

Enable lowering of statement function references in HLFIR. This follows
the same principle as statement function lowering with the current
lowering:
- Actual arguments are lowered and mapped to the statement function
dummy symbols.
- "HostAssociated" symbols are mapped to their host values (these are
the symbols referred to inside the statement function expressions that
are not statement function dummies. e.g: `x` in `stmt_func(i) =
x(i)`).
- The statement function expression is evaluated.
evaluate::SetLength has to be lowered to deal with statement functions
returning characters since the front-end is generating one to ensure the
statement function expression value is trimmed/padded to match the statement
function declared type.

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.
Lower procedure ref to user defined elemental procedure when:
- there are no arguments that may be dynamically optional
- for functions, the result has no length parameters
- the reference can be unordered
- there are not character by value arguments
This uses the recently added hlfir.elemental operation and tools.
The "core" of the argument preparation is shared between elemental
and non elemental calls (genUserCalls is code moved without any
functional changes)

This patch adds support for lowering intrinsics that have no dynamic
optionality aspects to handle and that requires argument to be lowered
to value, addr, or box.
It uses the current intrinsic lowering framework that can be re-used in
HLFIR to start with. HLFIR operations for charater/transformational
intrinsics will be added as needed from an optimization point of view.
The current approach will still create temporary variables for their
value directly in lowering.
Later patch will still need to add:
- support for dynamically optional arguments
- inquires
- "moving" the in memory computation of character and transformational
intrinsics to hlfir.expr. This is not needed from a semantic point of
view, but will help optimizing and will probably be required inside
hlfir.elemental returning characters so that the returned element
type is an hlfir.expr and match the result type of later hlfir.apply.

This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated. The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.
This is part of an effort to migrate from llvm::Optional to
std::optional:
https://discourse.llvm.org/t/deprecating-llvm-optional-x-hasvalue-getvalue-getvalueor/63716
Use recently added hlfir.associate/hlfir.end_associate to deal
with the cases where the actual argument is an expression.

Move genCallOpAndResult from ConvertExpr.cpp into a new file so that
it can be shared with lowering to FIR and HLFIR during the transition.
After the transition, call lowering to HLFIR will be implemented in
this new file.
