Short term solution: ROCm/rocMLIR#136

Long term solution: https://github.com/ROCmSoftwarePlatform/llvm-project-private/issues/142

Short term solution on exposing a structure from the Miir.h interface has been implemented and merged

Regarding on the long term solution, me && @atamazov synced offline and agreed that the short term solution is:

• Simple
• Good for speed

The solution does not has any apparent flaws for existing use cases. Therefore, I'm setting this ticket as low priority. We will implement any fix necessary when any of the below happened:

• libMLIRMIOpen get more matured with its interface overall, and we find it necessary to expose a different set of information from the interface
• The short term solution cannot satisfy all use case
• We have a breaking change in the runtime and structure flattening get dropped

@atamazov @jerryyin Is there still plan to implement the long term solution? If not, can we close this ticket? Thanks!

[atamazov]

@jerryyin Yep, maybe it's time to revise this ticket. What do you think?
