Even if there are no thread-safety concerns, we should not promote

provenance to perform the write. The @promote_global_noalias test

Worth noting that the load-only promotion may also not be well-defined

[flang] preserve pointer rank in polymorphic_pointer => NULL()
The current lowering for polymorphic pointer association was not
dealing with NULL in a "context aware" fashion: it was calling the
`PointerAssociate` runtime entry point with a fir.box<none> target.
But the fir.box<none> is a descriptor for a scalar, this lead the
runtime to set the pointer rank to zero, regardless of its actual
rank.
I do not think there is a way to expose this problem with the Fortran
code currently supported by flang, because most further manipulation of
the pointer would either set the rank correctly, or do not rely on the
rank in the runtime descriptor.
However, this is incorrect, and when assumed rank are supported, the
following would have failed:
```
subroutine check_rank(p)
class(*), pointer :: p(..)
p => null()
select rank(p)
rank (1)
print *, "OK"
rank default
print *, "FAILED"
end select
end subroutine
class(*), pointer :: p(:)
p => null()
call check_rank(p)
end

Instead, detect NULL() in polymorphic pointer lowering and trigger the
deallocation of the pointer.

[ORC] Add a generic bootstrap key-value store to SimpleRemoteEPC.
SimpleRemoteEPC already included a "bootstrap symbols map" that could be used
to communicate the addresses of symbols needed for JIT bootstrap. The new
bootstrap map can be used to communicate arbitrary bootstrap values (encoded as
SPS buffers).
The bootstrap symbols map is kept as distinct becasue bootstrap symbols are

logging (we know how to render the values) and tooling (e.g. utils for adding
