Kazu Hirata 9a41739565 [flang] Use std::nullopt instead of None (NFC)
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:

[flang] Lower type-bound procedure call needing dynamic dispatch to fir.dispatch
Lower call with polymorphic entities to fir.dispatch operation. This patch only
focus one lowering with simple scalar polymorphic entities. A follow-up patch
will deal with allocatble, pointer and array of polymorphic entities as they
require box manipulation for the passed-object.

[flang] Handle BINC(C) variables and add TODO for corner cases
- BIND(C) was ignored in lowering for objects (it can be used on
module and common blocks): use the bind name as the fir.global name.

- When an procedure is declared BIND(C) indirectly via an interface,
  it should have a BIND(C) name. This was not the case because
  GetBindName()/bindingName() return nothing in this case: detect this
  case in mangler.cpp and use the symbol name.

Add TODOs for corner cases:

- BIND(C) module variables may be initialized on the C side. This does
  not fit well with the current linkage strategy. Add a TODO until this
  is revisited.

- BIND(C) internal procedures should not have a binding label (see
  Fortran 2018 section 18.10.2 point 2), yet we currently lower them as
  if they were BIND(C) external procedure.
  I think this and the indirect interface case should really be
  handled by symbol.GetBindName instead of adding more logic in
  lowering to deal with this case: add a TODO.

Peter Klausler 52a1346b78 [flang] Distinguish intrinsic from non-intrinsic modules
For "USE, INTRINSIC", search only for intrinsic modules;
for "USE, NON_INTRINSIC", do not recognize intrinsic modules.
Allow modules of both kinds with the same name to be used in
the same source file (but not in the same scoping unit, a
constraint of the standard that is now enforced).

The symbol table's scope tree now has a single instance of
a scope with a new kind, IntrinsicModules, whose children are
the USE'd intrinsic modules (explicit or not).  This separate
"top-level" scope is a child of the single global scope and
it allows both intrinsic and non-intrinsic modules of the same
name to exist in the symbol table.  Intrinsic modules' scopes'
symbols now have the INTRINSIC attribute set.

The search path directories need to make a distinction between
regular directories and the one(s) that point(s) to intrinsic
modules.  I allow for multiple intrinsic module directories in
the second search path, although only one is needed today.

This module implements the lowering of Fortran intrinsics to the

libraries, etc.)

This revision is a tad larger because there are a large number of Fortran
