Make sure the invariant expressions are safe to expand. In
particular, we should not speculative a trapping division into
the preheader.

Fixes https://github.com/llvm/llvm-project/issues/62992.

The pass attaches attributes to operations for repro generation
purposes, but never removes them. This is not desirable when the pass
actually succeeds.

Conservatively return unknown in this degenerate case. This is
hard to hit in practice, because such phis are usually optimized
away before they reach a getObjectSize() call.

Fixes https://github.com/llvm/llvm-project/issues/63013.

They don't change inside the loop.

Seems unnecessary to create a StringRef here just so we can drop the
trailing null bytes. We can do that with the std::string we
create anyway.

We should preserve empty lines in output snippets.

Instead of creating a CaretLine the size of the SourceLine, just leave
it empty at first, let HighlightRange resize it to fit all the ~, then
resize it to fit the ^. Then we can save ourselves the work to remove
the trailing whitespace again.

printWordWrapped() is only called in one place, which passes all
parameters except `Indentation`. So, remove that parameter and use its
default value instead. Also remove the other default parameter values,
since those are unneeded.

They were both only called from one place and did very similar things.
Merge them into one, so we only have to iterate the source line once to
generate the SourceMap.

Instead of calling getDecomposedLoc() and then only using the FileID.

We don't use the offset returned from SourceManager::getDecomposedLoc
here, so we might as well just use getFileID().

Don't try to minimize the times we invoke operator<< on the output
stream by keeping a ToPrint string around. Instead, just print the
characters as we iterate over them.

Instead of always taking the last op from the worklist, take a random one. For testing/debugging purposes only. This feature can be used to ensure that lowering pipelines work correctly regardless of the order in which ops are processed by the GreedyPatternRewriteDriver.

The randomizer can be enabled by setting a numeric `MLIR_GREEDY_REWRITE_RANDOMIZER_SEED` option.

Note: When enabled, 27 tests are currently failing. Partly because FileCheck tests are looking for exact IR.
