Disabled the validation with ComputeAtMap since we now deal with non-conventional graph structures, so ComputeAtMap does not always work.

LGTM. Just one question about the test that's failing ComputeAtMap
| // Create a case where we're missing a valid concrete id so the compute at map | ||
| // processing will fail. We need to be able to create the concrete ID not just | ||
| // look for one. | ||

This example seems similar to this example we have looked at previously: https://github.com/NVIDIA/Fuser/pull/2512/files#diff-1e72aab35f54e7aaec2696293a478093301cc0a000d77fba8975cc8571740b84R731-R736. I am wondering why it fails, i.e. which dimension is missing a concrete ID?

This fusion has two paths from tv1. One is {tv2, tv3, tv4, tv5}, and another is {tv6, tv7, tv8, tv9}. The first group has [7, 11, 1], while the second has [7, 1, 13]. These two groups are inlined together at line 906, so the inlined loops need [7, 11, 13], however, none of the inlined tensors has the complete shape, and ComputeAtMap just fails as it can't find a valid concrete domain (at least, it isn't a silent failure).
IdModel's loop promotion can handle this inlining pattern as it automatically create a valid concrete domain. However, since we haven't completely replaced ComputeAtMap with IdModel, the lowering doesn't work yet.
It was moved to test_indexing_advanced.cpp in PR #3028. Looks like it got recovered likely when other PRs got merged.

Renamed test_gpu_indexing.cpp to test_indexing_advanced.cpp. Changed the tests to exercise both the legacy and new indexers.
Added several tests originally developed for IdModel (#32). Some of them are disabled as they are not yet supported.
