Arthur Eubanks	7de6dcd246	[Debugify] Skip debugifying on special/immutable passes ... With a function pass manager, it would insert debuginfo metadata before getting to function passes while processing the pass manager, causing debugify to skip while running the function passes. Skip special passes + verifier + printing passes. Compared to the legacy implementation of -debugify-each, this additionally skips verifier passes. Probably no need to update the legacy version since it will be obsolete soon. This fixes 2 instcombine tests using -debugify-each under NPM.

Vedant Kumar	d6ff43cc71	[Debugify] Export per-pass debug info loss statistics ... Add a -debugify-export option to opt. This exports per-pass `debugify` loss statistics to a file in CSV format. For some interesting numbers on debug value loss during an -O2 build of the sqlite3 amalgamation, see the review thread.
