Add support for generating reproducers on pass crash and failure. This cl adds support for generating a .mlir file containing a reproducer for crashes and failures that happen during pass execution. The reproducer contains a comment detailing the configuration of the pass manager(e.g. the textual description of the pass pipeline that the pass manager was executing), along with the original input module. Example Output: // configuration: -pass-pipeline='func(cse, canonicalize), inline' // note: verifyPasses=false module { ... } PiperOrigin-RevId: 274088134

// RUN: cat %t | FileCheck -check-prefix=REPRO %s
[mlir][Pass] Add support for generating local crash reproducers This revision adds a mode to the crash reproducer generator to attempt to generate a more local reproducer. This will attempt to generate a reproducer right before the offending pass that fails. This is useful for the majority of failures that are specific to a single pass, and situations where some passes in the pipeline are not registered with a specific tool.

Fix crash in the pass pipeline when local reproducer is enabled This crash only happens when a function pass is followed by a module pass. In this case the splitting of the pass pipeline didn't handle properly the verifier passes and ended up with an odd number of pass in the pipeline, breaking an assumption of the local crash reproducer executor and hitting an assertion.

// Check that we correctly handle verifiers passes with local reproducer, this use to crash.
// RUN: mlir-opt %s -test-function-pass -test-function-pass -test-module-pass -pass-pipeline-crash-reproducer=%t -pass-pipeline-local-reproducer
Make diagnostic a bit clearer. This prints out in case of any pass failure. Not just a crash. PiperOrigin-RevId: 283616719
