Avoid out-of-bound access when setting shape dimension size (#7650)

The number of implicit loops in a Linalg op can be greater than
the shape rank of the result. It's not always guaranteed that the
first batch of implicit loops are used to indexing into the output.
For example, for pooling ops, we have the following output 
indexing map:

```
(d0, d1, d2, d3, d4, d5) -> (d0, d1, d2, d5)>
```

Directly using the loop index to access the output shape will
cause out of bound access (at `d5` in the above).

This patch guards against such cases by considering implicit
loop to output shape dimension mapping.

IREE: Intermediate Representation Execution Environment

IREE (Intermediate Representation Execution Environment, pronounced as “eerie”) is an MLIR-based end-to-end compiler and runtime that lowers Machine Learning (ML) models to a unified IR that scales up to meet the needs of the datacenter and down to satisfy the constraints and special considerations of mobile and edge deployments.

See our website for project details, user guides, and instructions on building from source.

Project Status

IREE is still in its early phase. We have settled down on the overarching infrastructure and are actively improving various software components as well as project logistics. It is still quite far from ready for everyday use and is made available without any support at the moment. With that said, we welcome any kind of feedback on any communication channels!

  • MLIR topic within LLVM Discourse: IREE is enabled by and heavily relies on MLIR. IREE sometimes is referred to in certain MLIR discussions. Useful if you are also interested in MLIR evolution.
