[NFC] Add comments in unit test aix-xcoff-toc.ll to clarify the intent
Address David's post review comment in https://reviews.llvm.org/D71667.
Add comments to clarify what we are testing in that file.

[SelectionDAG] Fix copy/paste mistake in comment. NFC
I think this was copied from scalarizeVectorLoad where that is what
happens.

[TargetLowering][AMDGPU] Make scalarizeVectorLoad return a pair of
SDValues instead of creating a MERGE_VALUES node. NFCI
This allows us to clean up some places that were peeking through the
MERGE_VALUES node after the call. By returning the SDValues directly, we
can clean that up.
Unfortunately, there are several call sites in AMDGPU that wanted the
MERGE_VALUES and now need to create their own.

Commit 0d6ebb4f0dd7ca81bdfc2a210b1d5ef46e0c9587 by riverriddle
[mlir] Refactor operation results to use a single use list for all
results of the operation.
Summary: A new class is added, IRMultiObjectWithUseList, that allows for
representing an IR use list that holds multiple sub values(used in this
case for OpResults). This class provides all of the same functionality
as the base IRObjectWithUseList, but for specific sub-values. This saves
a word per operation result and is a necessary step in optimizing the
layout of operation results. For now the use list is placed on the
operation itself, so zero-result operations grow by a word. When the
work for optimizing layout is finished, this can be moved back to being
a trailing object based on memory/runtime benchmarking.

Commit 5b1cbfa4232ee81e62a16534113aeb7401841f82 by shengchen.kan
[NFC] Style cleanup
1. Remove function is64BitMode() and use STI.hasFeature(X86::Mode16Bit)
directly 2. Use Doxygen features in comment 3. Rename functions to make
them start with a lower case letter 4. Format the code with clang-format

Revert "DebugInfo: Fix rangesBaseAddress DICompileUnit bitcode
serialization/deserialization"
Seeing some curious CFI failures internally - which makes little sense
to me, as I don't think anyone is using this flag (even us,
internally)... so sounds like a bug in my code somewhere (possibly a
latent one that propagating this flag exposed, not sure). Reverting
while I investigate.
This reverts commit c51b45e32ef7f35c11891f60871aa9c2c04cd991.
