[OpenMP][IR-Builder] Introduce the finalization stack
As a permanent and generic solution to the problem of variable
finalization (destructors, lastprivate, ...), this patch introduces the
finalization stack. The objects on the stack describe (1) the
(structured) regions the OpenMP-IR-Builder is currently constructing,
(2) if these are cancellable, and (3) the callback that will perform the
finalization (=cleanup) when necessary.
As the finalization can be necessary multiple times, at different source
locations, the callback takes the position at which code is currently
generated. This position will also encode the destination of the "region
exit" block *iff* the finalization call was issues for a region
generated by the OpenMPIRBuilder. For regions generated through the old
Clang OpenMP code geneneration, the "region exit" is determined by Clang
inside the finalization call instead (see getOMPCancelDestination).
As a first user, the parallel + cancel barrier interaction is changed.
In contrast to the temporary solution before, the barrier generation in
Clang does not need to be aware of the "CancelDestination" block.
Instead, the finalization callback is and, as described above, later
even that one does not need to be.

[Attributor] UB Attribute now handles all instructions that access memory through a pointer
Summary:
Follow-up on: https://reviews.llvm.org/D71435
We basically use `checkForAllInstructions` to loop through all the instructions in a function that access memory through a pointer: load, store, atomicrmw, atomiccmpxchg
Note that we can now use the `getPointerOperand()` that gets us the pointer operand for an instruction that belongs to the aforementioned set.
Question: This function returns `nullptr` if the instruction is `volatile`. Why?
Guess: Because if it is volatile, we don't want to do any transformation to it.
Another subtle point is that I had to add AtomicRMW, AtomicCmpXchg to `initializeInformationCache()`. Following `checkAllInstructions()` path, that
seemed the most reasonable place to add it and correct the fact that these instructions were ignored (they were not in `OpcodeInstMap` etc.). Is that ok?

[lldb][NFC] Remove ClangExternalASTSourceCommon
ClangExternalASTSourceCommon's purpose is to store a map from
Decl*/Type* to ClangASTMetadata. Usually this data is accessed
via the ClangASTContext interface which then grabs the
current ExternalASTSource of its ASTContext, tries to cast it
to ClangExternalASTSourceCommon and then accesses the metadata
map. If the casting fails the setter does nothing and the getter
returns a nullptr as if there was no known metadata for a type/decl.
This system breaks as soon as any non-LLDB ExternalASTSource is added via
a multiplexer to our existing ExternalASTSource (in which case we suddenly
loose all out metadata as the casting always fails with an ExternalASTSource
that is not inheriting from ClangExternalASTSourceCommon).
This patch moves the metadata map to the ClangASTContext. This gets
rid of all the fragile casting, the requirement that every ExternalASTSource in
LLDB has to inherit from ClangExternalASTSourceCommon and simplifies
the metadata implementation to a simple map lookup. As ClangExternalASTSourceCommon
had no other purpose than storing metadata, this patch deletes this class
and replaces all uses with clang::ExternalASTSource.
No other code changes in this commit beside the AppleObjCDeclVendor which
was the only code that did not use the ClangASTContext interface but directly
accessed the ClangExternalASTSourceCommon.

[clang] [ast] CXXRecordDecl::getVisibleConversionFunctions() could be const
The function and its called static helpers don't modify the received
CXXRecordDecl arguments at all as the method's result is put into an
output parameter. Thus they can be const which allows for neatly
grabbing the conversion methods in a context where we only have a const
ASTUnit at hand.

[llvm-readobj] - Remove an excessive helper for printing dynamic tags.
This removes the `getTypeString` from readeobj source because it
almost duplicates the existent method: `ELFFile<ELFT>::getDynamicTagAsString`.
Side effect: now it prints "<unknown:>0xHEXVALUE" instead of "(unknown)" for unknown values.

```
0x0000000012345678 (unknown) 0x8765432187654321

Refactor the way that pass options are specified.
This change refactors pass options to be more similar to how statistics are modeled. More specifically, the options are specified directly on the pass instead of in a separate options class. (Note that the behavior and specification for pass pipelines remains the same.) This brings about several benefits:
* The specification of options is much simpler
* The round-trip format of a pass can be generated automatically
* This gives a somewhat deeper integration with "configuring" a pass, which we could potentially expose to users in the future.

The CFGBlock::getLastCondition was not prepared for static initializer

This patch also revamps CFG unit tests. Earlier the lifetime of the AST

were dangling. This was OK, since none of the tests dereferenced those
pointers. This was, however, a timed bomb. There were patches in the

Change the `notifyRootUpdated` API to be transaction based.
This means that in-place, or root, updates need to use explicit calls to `startRootUpdate`, `finalizeRootUpdate`, and `cancelRootUpdate`. The major benefit of this change is that it enables in-place updates in DialectConversion, which simplifies the FuncOp pattern for example. The major downside to this is that the cases that *may* modify an operation in-place will need an explicit cancel on the failure branches(assuming that they started an update before attempting the transformation).
