[CGSCC] Detect devirtualization in more cases
The devirtualization wrapper misses cases where if it wraps a pass
manager, an individual pass may devirtualize an indirect call created by
a previous pass. For example, inlining may create a new indirect call
which is devirtualized by instcombine. Currently the devirtualization
wrapper will not see that because it only checks cgscc edges at the very
beginning and end of the pass (manager) it wraps.
This fixes some tests testing this exact behavior in the legacy PM.
Instead of checking WeakTrackingVHs for CallBases at the very beginning
and end of the pass it wraps, check every time
updateCGAndAnalysisManagerForPass() is called.
check-llvm and check-clang with -abort-on-max-devirt-iterations-reached
on by default doesn't show any failures outside of tests specifically
testing it so it doesn't needlessly rerun passes more than necessary.
(The NPM -O2/3 pipeline run the inliner/function simplification pipeline
under a devirtualization repeater pass up to 4 times by default).
http://llvm-compile-time-tracker.com/?config=O3&stat=instructions&remote=aeubanks
shows that 7zip has ~1% compile time regression. I looked at it and saw
that there indeed was devirtualization happening that was not previously
caught, so now it reruns the CGSCC pipeline on some SCCs, which is WAI.

Build reproducible tarballs for releases
Currently the tarballs contain superfluous metadata, like the user name
of the packager and via Pax headers even the PID of the tar process that
packaged the files. We build the monorepo projects directly from the git
repo using "git archive" and for the test-suite we add some flags as
recommended by https://reproducible-builds.org/docs/archives/. We don't
use numeric owners though to be compatible with "git archive".
The advantage of "git archive" is that the releaser doesn't have to
download the tar ball and extract it, rather the archive is built
directly from the repository. This is probably what GitHub uses
internally to produce the tarballs, so I wouldn't expect a difference.
