value() is a 15.0.0 API for std::optional migration.
std::optional::value() has undesired exception checking semantics and is
unavailable in older Xcode (see
_LIBCPP_AVAILABILITY_BAD_OPTIONAL_ACCESS). Deprecate value() to prevent
new in-tree uses which may accidentally cause build breakage for older
Xcode when contributors perform std::optional migrating.
Some downtream MLIR projects such as tensorflow/mlir-hlo, stablehlo use
value(), so we do not remove it now.

[flang] Check for another case of ambiguous generic resolution
When specific procedures of a generic have dummy procedures,
underspecified actual procedures can match more than one specific
procedure. This can happen with actual procedures that are
externals with implicit interfaces, including the completely
unspecified case of a PROCEDURE() or EXTERNAL that doesn't even
differentiate between a subroutine and a function.
Generic resolution can already handle cases of ambiguous resolution
due to the use of NULL() actual arguments with no MOLD= arguments
to define their types. Extend the handling of ambiguous actual
arguments to include the case of underspecified actual procedures.

Constraint C1529 requires that the base object of a type-bound procedure
reference be a scalar if the TBP has the NOPASS attribute. Most
compilers do not enforce this constraint and it does not appear to
have any implementation justification, so emit portability warning.
On the other hand, we fail to enforce C919 for references to
procedure pointer components, whose base objects must of course
be scalars in order to avoid ambiguity and empty arrays, whether
NOPASS is present or not.
