Addresses and properties (bounds, length parameters) of host
variables associated in an internal procedure were all passed via
an extra tuple argument of the internal procedure.
This extra tuple is in general an overhead: it must be created and
passed, and require creating thunks when taking the address of the
internal procedure.
This patch allows not using the tuple for host global variables
(from modules, common block, or local saved variables) since they can
be instantiated from the fir.global symbol in the internal procedure
instead.
Add a fir.internal_proc attribute to mlir::FuncOp for internal procedures
so that ArrayValueCopy can still detect internal procedures even if they
do not have a tuple argument.

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:

It seems the needed functionality was already implemented for host associations,
so turn that code into a function and move it into a (hopefully appropriate)
common location and reuse it.

An ASSOCIATE or SELECT TYPE statement's selector whose "right-hand side" is the result
of a reference to a function that returns a pointer must be usable as a valid target
(but not as a pointer).

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 removes any potential confusion with the `getType` accessors
which correspond to SSA results of an operation, and makes it
clear what the intent is (i.e. to represent the type of the function).
