aa3af9e053 ARC Analysis in one pass v3 (#17068) 
* Analyse last reads all at once

* Integrate firstWrite analysis

* Small cleanup

* Use sets instead of seqs

* Remove instrTargets

* Reap the benefits

* Implement error diagnostics

* Operate on DFA index for lastRead analysis

* Use mgetOrPut

* Cache alias results

This improves performance by a lot, since many
CFG locations map to a single PNode

* Improve performance

* Improve performance

* Cleanup

* Fix #17025

* Grammar

* Expand testcase
