[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.

[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. Differential Revision: https://reviews.llvm.org/D49003 llvm-svn: 337787
