update_test_checks: improve IR value name stability (#110940)
By default, UTC attempts to keep the produced diff small by keeping IR value name variables stable. The old algorithm was roughly: 1. Compute a diff between the old and new check lines, where "uncommitted" variable names are replaced by a wildcard. This leads to a set of non-crossing "candidate" pairs of (old line, new line) that we can try to make equal. 2. Greedily walk this list of candidates, committing to variable names that make candidate lines equal if possible. The greedy approach in the second step has the downside that committing to a variable name greedily can sometimes prevent many subsequent candidates from getting the variable name assignment that would make them equal. We keep the first step as-is, but replace the second one by an algorithm that finds a large independent set of candidates, i.e. candidate pairs of (old line, new line) which are non-conflicting in the sense that their desired variable name mappings are not in conflict. We find the large independent set by greedily assigning a coloring to the conflict graph and taking the largest color class. We then commit to all the variable name mappings which are desired by candidates in this largest color class. As before, we then recurse into regions between matching lines. This is required in large cases. For example, running this algorithm at the top-level of the new test case (stable_ir_values5.ll) matches up most of the instructions, but not the names of the result values of all the `load`s. This is because (unlike e.g. the getelementptrs) the load instructions are all equal except for variable names, and so step 1 (the diff algorithm) doesn't consider them as candidates. However, they are trivially matched by recursion. This also happens to fix a bug in tracking line indices that went unnoticed previously... As is usually the case with these changes, the quality improvement is hard to see from the diff of this patch. However, it becomes obvious when comparing the diff of stable_ir_values5.ll against stable_ir_value5.ll.expected before and after this change.
