[flang][NFC] use llvm.intr.stacksave/restore instead of opaque calls (#108562)
The new LLVM stack save/restore intrinsic operations are more convenient
than function calls because they do not add function declarations to the
module and therefore do not block the parallelisation of passes.
Furthermore they could be much more easily marked with memory effects
than function calls if that ever proved useful.
This builds on top of #107879.
Resolves #108016

[flang] Enable polymorphic lowering by default (#83285)
Polymorphic entity lowering status is good. The main remaining TODO is
to allow lowering of vector subscripted polymorphic entity, but this
does not deserve blocking all application using polymorphism.
Remove experimental option and enable lowering of polymorphic entity by
default.

[flang] Lower procedure pointer components (#75453)
Lower procedure pointer components, except in the context of structure
constructor (left TODO).
Procedure pointer components lowering share most of the lowering logic
of procedure poionters with the following particularities:
- They are components, so an hlfir.designate must be generated to
retrieve the procedure pointer address from its derived type base.
- They may have a PASS argument. While there is no dispatching as with
type bound procedure, special care must be taken to retrieve the derived
type component base in this case since semantics placed it in the
argument list and not in the evaluate::ProcedureDesignator.
These components also bring a new level of recursive MLIR types since a
fir.type may now contain a component with an MLIR function type where
one of the argument is the fir.type itself. This required moving the
"derived type in construction" stackto the converter so that the object
and function type lowering utilities share the same state (currently the
function type utilty would end-up creating a new stack when lowering its
arguments, leading to infinite loops). The BoxedProcedurePass also
needed an update to deal with this recursive aspect.
