When running the `flang/test/HLFIR/simplify-hlfir-intrinsics.fir` test
case on AIX we encounter issues building op as they are not found in the
mlir context:
```
LLVM ERROR: Building op `arith.subi` but it isn't known in this MLIRContext: the dialect may not be loaded or this operation hasn't been added by the dialect. See also https://mlir.llvm.org/getting_started/Faq/#registered-loaded-dependent-whats-up-with-dialects-management
LLVM ERROR: Building op `hlfir.yield_element` but it isn't known in this MLIRContext: the dialect may not be loaded or this operation hasn't been added by the dialect. See also https://mlir.llvm.org/getting_started/Faq/#registered-loaded-dependent-whats-up-with-dialects-management

```
The issue is caused by the "Merge disjoint stack slots" pass and the
error is not present if the source is built with `-mllvm
--no-stack-coloring`
Thanks to investigation by @stefanp-ibm we found that "the
initializer_list {inputIndices[1], inputIndices[0]} has a lifetime that
only exists for the range of the constructor for ValueRange. Once we get
to stack coloring we merge the stack slot for that element with another
stack slot and then it gets overwritten which corrupts
transposedIndices"
The changes below prevents the corruption of transposedIndices and
passes the test case.

To properly create temporary array for a polymorphic result
of hlfir.elemental we need to keep the mold as its operand.
This patch adds just the basic support.

hlfir.count lowering was using incorrect default integer kind
by ignoring the kind specified in the ModuleOp.

This patch adds 'unordered' attribute handling the HLFIR elementals'
builders and fixes the attribute handling in lowering and transformations.
Depends on D154031, D154032

It seems just replacing the operation was not replacing all of the uses
when the types of the expression before and after this pass differ (due
to differing shape information). Now the shape information is always
kept the same.

Inlining as a hlfir.elemental will allow the transpose to be inlined
into subsequent operations in some cases. For example,
y = TRANSPOSE(x)
z = y * 2
Will operate in a single loop without creating a temporary for the
TRANSPOSE (unlike the runtime call, which always allocates).
This is in a new SimplifyHLFIRIntriniscs pass. The intention is that some
day that pass might replace the FIR SimplifyIntrinsics pass.
