When `ExpressionAnalyzer::AnalyzeCall` processed a subroutine it was
always returning std::nullopt. Change it to return a `ProcedureRef`
wrapped in an `Expr` so that it can be saved in `CallStmt::typedCall`.

When dumping the parse tree, if there are analyzed expressions,
assignments, or call statements, include the Fortran form of those
in the dump.
This uses the same `AnalyzedObjectsAsFortran` object that unparsing
does so it applies to the same nodes.
We already do something like this for `Name` nodes as well as some
predefined types, so abstract it into an `AsFortran` function which
returns the Fortran source for a node that is to be included in the
dump.

Add `ArgumentAnalyzer::FindBoundOp` to look for an operator or
assignment definition in the type of each operand. Then `TryBoundOp`
checks if it is actually applicable.
Change ResolveGeneric to handle type-bound operators: the `adjustActuals`
function passed in handles the difference between these and normal
type-bound procedures. For operators, either operand may be the passed-
object argument. For procedures we know which one it is.
Extract `GetDerivedTypeSpec`, `GetBindingResolution`, and
`OkLogicalIntegerAssignment` into separate functions to simplify the
logic of the calling functions.

Add new license text to runtime/magic-numbers.h, which is unusual
in that it is the only .h file in flang that is intended to be
included in either C or Fortran files. This requires special
handling of the license text.

Extend `ResolveGeneric` to handle calls to procedure components by
passing in the data-ref that is used as the passed-object argument.
`AddPassArg` takes care of adding a placeholder for the passed object.
This is shared by the generic and non-generic cases of calls to
procedure components.

The real operand was always converted to the complex operand type.
The highest precison should be used instead. This fix converts the
real to a complex of the same kind before applying the promotion
rules for complex operands.
Reference to Fortran 2018 standard 10.9.1.3 that rules this added
in comments.

identification of their index in the dummy argument list,
simplifying their representation, completing the representation
of their actual arguments, and (while I'm here) resolving
calls to type-bound procedures whose bindings are known at
compilation time.
Button up class ActualArgument by making remaining data
members private and adding accessors & mutators.

1. Dump negative parts in complex constants without parentheses
(-1., 0.) was dumped as ((-1.), 0.) from f18 expression format.
The latter format is only valid with the complex constructor extension
that is not supported by all compilers.
This commit ensure the former fromat is used in dumps so that dumps can
be used by all fortran compilers. It turns out the parenthesis added
by REAL::AsFortran are not required because operation lowering is
already taking care of this.
2. Dump evaluate::ComplexComponent with REAL/IMAG instead of %RE/%IM
f18 was failing to reparse its own dump in some cases involving
complex expressions like `-z**i`.
The reason was %RE and %IM were used to dump ComplexComponents.
%RE and %IM can only be used on designators but ComplexComponent can
contain arbitrary complex expressions.
Hence, %RE and %IM cannot be used to dump ComplexComponent.
This commit replace them with call to intrinsic function
REAL/IMAG.
Note that this may unfortunatly be unsafe if the user
shadowed REAL or IMAG but I do not see an easy way to solve
this... The current dump is not correct.
