[llvm-lto] Remove support for legacy pass manager
This removes support for the legacy pass manager in llvm-lto and
llvm-lto2. In this case I've dropped the use-new-pm option entirely,
as I don't think this is considered part of the public interface.
This also makes -debug-pass-manager work with llvm-lto, because
that was needed to migrate some tests to NewPM.

The bot failure should be fixed by D73418, committed as
af954e441a5170a75687699d91d85e0692929d43.
I also added a fix for non-x86 bot failures by requiring x86 in new test
lld/test/ELF/lto/devirt_vcall_vis_public.ll.

[LTO/WPD] Enable aggressive WPD under LTO option
Summary:
Third part in series to support Safe Whole Program Devirtualization
Enablement, see RFC here:
http://lists.llvm.org/pipermail/llvm-dev/2019-December/137543.html
This patch adds type test metadata under -fwhole-program-vtables,
even for classes without hidden visibility. It then changes WPD to skip
devirtualization for a virtual function call when any of the compatible
vtables has public vcall visibility.
Additionally, internal LLVM options as well as lld and gold-plugin
options are added which enable upgrading all public vcall visibility
to linkage unit (hidden) visibility during LTO. This enables the more
aggressive WPD to kick in based on LTO time knowledge of the visibility
guarantees.
Support was added to all flavors of LTO WPD (regular, hybrid and
index-only), and to both the new and old LTO APIs.
Unfortunately it was not simple to split the first and second parts of
this part of the change (the unconditional emission of type tests and
the upgrading of the vcall visiblity) as I needed a way to upgrade the
public visibility on legacy WPD llvm assembly tests that don't include
linkage unit vcall visibility specifiers, to avoid a lot of test churn.
I also added a mechanism to LowerTypeTests that allows dropping type
test assume sequences we now aggressively insert when we invoke
distributed ThinLTO backends with null indexes, which is used in testing
mode, and which doesn't invoke the normal ThinLTO backend pipeline.
Depends on D71907 and D71911.

[ThinLTO/WPD] Remove an overly-aggressive assert
Summary:
An assert added to the index-based WPD was trying to verify that we only
have multiple vtables for a given guid when they are all non-external
linkage. This is too conservative because we may have multiple external
vtable with the same guid when they are in comdat. Remove the assert,
as we don't have comdat information in the index, the linker should
issue an error in this case.
See discussion on D71040 for more information.
