I have made the required changes to both PRs to update the representation for
the DeclMapperOp.
Some changes I've incorporated are:
Inside DeclMapperOp's region I've introduce a new `DeclMapperInfoOp` to which
I've attached the `MapClause`. Not having any `MapClause` explicitly associated
seemed weird to me, also walking through the region collecting all the
`MapInfoOps` for processing in various places in the code base seemed like a
bad design to me.
Also, instead of using the block arg, I've created a `temporary alloca` inside
the region. This is to save the hassle of binding the block_arg to the symbol,
binding the `alloca` is much more straightforward.
We can drop the entire `DeclMapperOp` including the region once it reaches
`OpenMPTOLLVMIRTranslation`.
Let me what are your thoughts on this approach :)
