An unlimited polymoprhic entity can be allocated with a derived type
spec or an intrinsic type spec. This patch add the generation of the
runtime function call when the allocation is done with an intrinsic
type spec.

When emboxing an entity to a polymorphic box, use the input type to
compute the type code and element size as the box type is too generic.
When reboxing a polymorphic box, get this information from the input
box.

Following RFC at
https://discourse.llvm.org/t/rfc-ffp-contract-default-value/66301
This adds the `fastmath<contract>` attribute to `fir.call` and some
floating point arithmetic operations (hence the many test changes).
Instead of testing for this specific attribute, I am using a regular
expression to match any attributes.
This patch forces pointer and allocatable polymorphic entities to be
tracked as descriptor. It also enables the pointer assignment between
polymorphic entities. Pointer association between a non-polymorphic
pointer and a polyrmophic target might require some more work as
per 10.2.2.3 point 1.

This patch fix issues found during call to deallocate.
fir.class can be handled the same way as fir.box in fir.store operation
code generation. In MutableBox::createNewFirBox, the fir.class is
also already a boxed entity.

The runtime function `AllocatableDeallocate/PointerDeallocate` is reponsible to
deallocate and finalize it. This patch just adds tests to make sure the correct
runtime function is called.

Dynamic type of a polymorphic array element was retrieved by finding the
coordinate operation and use the base array. This patch remove this hack and use
the newly PolymorphicValue to carray the dynamic type together with the element.
The patch also rearrange some tests in the `allocatable-polymorphic.f90`.

In order to be passed as passed-object in the dynamic dispatch, the
polymorphic pointer entity are emboxed. In this process, the dynamic
type must be preserve and pass to fir.embox as the tdesc operand. This
patch introduce a new ExtendedValue that allow to carry over the
dynamic type when the value is unboxed.

Lowering of allocate statement for polymoprhic pointers is a bit
different than for allocatables. A call to `PointerNullifyDerived`

For polymoprhic entities, the type descriptor is dynamic. The tdesc
operand on fir.embox is meant to propagate the dynamic type when
embox a polymorphic entity.
This patch makes use of this operand in code generation and update
the created descriptor accordingly.

When allocating a polymorphic entity, its type descriptor can come
from the declared type or can be provided in the allocate statement.
This patch adds lowering for allocate on polymorphic by calling
the `AllocatableInitDerived` runtime function with the correct
type descriptor. Some adaptation are made in the code generation
to accept fir.class where it is appropriate.
