Currently, getVA() returns a virtual address with the assumption that

I'm finding that I have to add and subtract ImageBase in several places

[NFCi] Iterative Outliner + clang-format refactoring.
Prior to D69446 I had done some NFC cleanup to make landing an iterative
outliner a cleaner more straight-forward patch. Since then, it seems that has
landed but I noticed some ways it could be cleaned up. Specifically:
1) doOutline was meant to be the re-runable function, but instead
runOnceOnModule was created that just calls doOutline.
2) In D69446 we discussed that the flag allowing the re-run of the
outliner should be a flag to tell how many additional times to run
the outliner again, not the total number of times. I don't think it
makes sense to introduce a flag, but print an error if the flag is
set to 0.
This is an NFCi, the i being that I get rid of the way that the
machine-outline-runs flag could be used to tell the outliner to not run
at all, and because I renamed the flag to '-machine-outliner-reruns'.

AArch64's system register ERXTS_EL1 is present in the backend as a
component of the Arm Reliability, Availability and Serviceability (RAS)
extension. However, it has been removed from the specification before
its final release.
This patch removes the register.

[lldb/DWARF] Fix a split-dwarf crash while parsing compile units
The cause of this crash is relatively simple -- we are using a
SymbolFileDWARFDwo to parse a (skeleton) dwarf unit. This cause the
CompileUnit to be created with the wrong ID, which later triggers an
assertion in SymbolFile::SetCompileUnitAtIndex. The fix is also simple
-- ensure we use the right symbol file for parsing.
However, a fairly elaborate setup is needed trigger this bug, because
ParseCompileUnit is normally called very early on (and with the right
symbol file object) during the process of accessing a compile unit.
The only way this can be triggered is if the DWARF unit is
"accidentally" pulled into scope during expression evaluation
This can happen if the "this" object used for the context of an
expression is in a namespace, and that namespace is also present in
other compile units
The included test recreates this setup.

[TTI] Add DemandedElts to getScalarizationOverhead
The improvements to the x86 vector insert/extract element costs in D74976 resulted in the estimated costs for vector initialization and scalarization increasing higher than should be expected. This is particularly noticeable on pre-SSE4 targets where the available of legal INSERT_VECTOR_ELT ops is more limited.
This patch does 2 things:
1 - it implements X86TTIImpl::getScalarizationOverhead to more accurately represent the typical costs of a ISD::BUILD_VECTOR pattern.
2 - it adds a DemandedElts mask to getScalarizationOverhead to permit the SLP's BoUpSLP::getGatherCost to be rewritten to use it directly instead of accumulating raw vector insertion costs.
This fixes PR45418 where a v4i8 (zext'd to v4i32) was no longer vectorizing.
A future patch should extend X86TTIImpl::getScalarizationOverhead to tweak the EXTRACT_VECTOR_ELT scalarization costs as well.

[analyzer] Track runtime types represented by Obj-C Class objects
Summary:
Objective-C Class objects can be used to do a dynamic dispatch on
class methods. The analyzer had a few places where we tried to overcome
the dynamic nature of it and still guess the actual function that
is being called. That was done mostly using some simple heuristics
covering the most widespread cases (e.g. [[self class] classmethod]).
This solution introduces a way to track types represented by Class
objects and work with that instead of direct AST matching.
