[NewPM][LVI] Abandon LVI after CVP ...
As mentioned on D70376, LVI can currently cause performance issues
when running under NewPM. The problem is that, unlike the legacy
pass manager, NewPM will not immediately discard the LVI analysis
if the following pass does not need it. This is a problem, because
LVI has a high memory requirement, and mass invalidation of LVI
values is very inefficient. LVI should only be alive during passes
that actively interact with it.
This patch addresses the issue by explicitly abandoning LVI after CVP,
which gets us back to the LegacyPM behavior.
