[ARM] Extra MVE VADDV reduction patterns
We already make use of the VADDV vector reduction instruction for cases
where the input and the output start out at the same type. The MVE
instruction however will sum into an i32, so if we are summing a v16i8
into an i32, we can still use the same instructions. In terms of IR,
this looks like a sext of a legal type (v16i8) into a very illegal type
(v16i32) and a vecreduce.add of that into the result. This means we have
to catch the pattern early in a DAG combine, producing a target VADDVs/u
node, where the signedness is now important.
This is the first part, handling VADDV and VADDVA. There are also
VADDVL/VADDVLA instructions, which are interesting because they sum into
a 64bit value. And VMLAV and VMLALV, which are interesting because they
also do a multiply of two values. It may look a little odd in places as
a result.

[lldb] Let TypeSystemClang::GetDisplayTypeName remove anonymous and inline namespaces.
Summary:
Currently when printing data types we include implicit scopes such as inline namespaces or anonymous namespaces.
This leads to command output like this (for `std::set<X>` with X being in an anonymous namespace):
```
(lldb) print my_set
(std::__1::set<(anonymous namespace)::X, std::__1::less<(anonymous namespace)::X>, std::__1::allocator<(anonymous namespace)::X> >) $0 = size=0 {}
```
This patch removes all the implicit scopes when printing type names in TypeSystemClang::GetDisplayTypeName
so that our output now looks like this:
```
(lldb) print my_set
(std::set<X, std::less<X>, std::allocator<X> >) $0 = size=0 {}
```
As previously GetDisplayTypeName and GetTypeName had the same output we actually often used the
two as if they are the same method (they were in fact using the same implementation), so this patch also
fixes the places where we actually want the display type name and not the actual type name.
Note that this doesn't touch the `GetTypeName` class that for example the data formatters use, so this patch
is only changes the way we display types to the user. The full type name can also still be found when passing
'-R' to see the raw output of a variable in case someone is somehow interested in that.

[Coroutines][4/6] New pass manager: coro-cleanup
Summary:
Depends on https://reviews.llvm.org/D71900.
The fourth in a series of patches that ports the LLVM coroutines passes
to the new pass manager infrastructure. This patch implements
'coro-cleanup'.
No existing regression tests check the behavior of coro-cleanup on its
own, so this patch adds one. (A test named 'coro-cleanup.ll' exists, but
it relies on the entire coroutines pipeline being run. It's updated to
test the new pass manager in the 5th patch of this series.)

[mlir] Refactor TypeConverter to add conversions without inheritance
Summary:
This revision refactors the TypeConverter class to not use inheritance to add type conversions. It instead moves to a registration based system, where conversion callbacks are added to the converter with `addConversion`. This method takes a conversion callback, which must be convertible to any of the following forms(where `T` is a class derived from `Type`:
* Optional<Type> (T type)
- This form represents a 1-1 type conversion. It should return nullptr
or `llvm::None` to signify failure. If `llvm::None` is returned, the
converter is allowed to try another conversion function to perform
the conversion.
* Optional<LogicalResult>(T type, SmallVectorImpl<Type> &results)
- This form represents a 1-N type conversion. It should return
`failure` or `llvm::None` to signify a failed conversion. If the new
set of types is empty, the type is removed and any usages of the
existing value are expected to be removed during conversion. If
`llvm::None` is returned, the converter is allowed to try another
conversion function to perform the conversion.
When attempting to convert a type, the TypeConverter walks each of the registered converters starting with the one registered most recently.

make the Observer be available in various parts of code and to avoid

[IR] Lazily number instructions for local dominance queries
Essentially, fold OrderedBasicBlock into BasicBlock, and make it
auto-invalidate the instruction ordering when new instructions are
added. Notably, we don't need to invalidate it when removing
instructions, which is helpful when a pass mostly delete dead
instructions rather than transforming them.
The downside is that Instruction grows from 56 bytes to 64 bytes. The
resulting LLVM code is substantially simpler and automatically handles
invalidation, which makes me think that this is the right speed and size
tradeoff.
The important change is in SymbolTableTraitsImpl.h, where the numbering
is invalidated. Everything else should be straightforward.
We probably want to implement a fancier re-numbering scheme so that
local updates don't invalidate the ordering, but I plan for that to be
future work, maybe for someone else.
