ArrayRef: Put back std::equal for operator== with a check for the empty ArrayRefs
This has the nice property of compiling down to memcmp when feasible. An empty
ArrayRef can have a nullptr in its Data field. I didn't find anything in the
standard speaking against std::equal(nullptr, nullptr, nullptr) begin valid but
MSVC asserts. The way libstdc++ lowers std::equal down to memcmp also makes
invoking std::equal with a nullptr undefined behavior so checking is the only
way to be safe.

DebugInfo: Fix invalid file reference in CodeGen/X86/unknown-location.ll
There are two types of files in the old (current) debug info schema.
!0 = !{!"some/filename", !"/path/to/dir"}
!1 = !{!"0x29", !0} ; [ DW_TAG_file_type ]
!1 has a wrapper class called `DIFile` which inherits from `DIScope` and
is referenced in 'scope' fields.
!0 is called a "file node", and debug info nodes with a 'file' field
point at one of these directly -- although they're built in `DIBuilder`
by sending in a `DIFile` and reaching into it.
In the new hierarchy, I unified these nodes as `MDFile` (which `DIFile`
is a lightweight wrapper for) in r230057. Moving the new hierarchy into
place (and upgrading testcases) caused CodeGen/X86/unknown-location.ll

.loc 2 4 3

.loc 1 4 3

DebugInfo: Use TempMDNode in DIDescriptor::replaceAllUsesWith()
Start using `TempMDNode` in `DIDescriptor::replaceAllUsesWith()`
(effectively `std::unique_ptr<MDNode, MDNode::deleteTemporary>`).
Besides making ownership more explicit, this prepares for when
`DIDescriptor` refers to nodes that are *not* `MDTuple`. The old logic
for "replacing" a node with itself used `MDNode::get()` to return a new
(uniqued) `MDTuple`, while the new logic just defers to
`MDNode::replaceWithUniqued()` (which also typically saves an allocation
and RAUW traffic by mutating the temporary in place).

Optimize metadata node fields for CHECK-ability
While gaining practical experience hand-updating CHECK lines (for moving
the new debug info hierarchy into place), I learnt a few things about
CHECK-ability of the specialized node assembly output.
- The first part of a `CHECK:` is to identify the "right" node (this
is especially true if you intend to use the new `CHECK-SAME`
feature, since the first CHECK needs to identify the node correctly
before you can split the line).
- If there's a `tag:`, it should go first.
- If there's a `name:`, it should go next (followed by the
`linkageName:`, if any).
- If there's a `scope:`, it should follow after that.
- When a node type supports multiple DW_TAGs, but one is implied by
its name and is overwhelmingly more common, the `tag:` field is
terribly uninteresting unless it's different.
- `MDBasicType` is almost always `DW_TAG_base_type`.
- `MDTemplateValueParameter` is almost always
`DW_TAG_template_value_parameter`.
- Printing `name: ""` doesn't improve CHECK-ability, and there are far
more nodes than I realized that are commonly nameless.
- There are a few other fields that similarly aren't very interesting
when they're empty.
This commit updates the `AsmWriter` as suggested above (and makes
necessary changes in `LLParser` for round-tripping).

When using SetConsoleTextAttribute() to set the foreground or

This is annoying when you have a non default console background

MachineDominators: Move applySplitCriticalEdges into the cpp file.
It's too big for inlining anyways. Also clean it up slightly. No functionality
change intended.

[PowerPC] Fix PR22711 - Misaligned .toc section
Straightforward patch to emit an alignment directive when emitting a
TOC entry. The test case was generated from the test in PR22711 that
demonstrated a misaligned .toc section. The object code is run
through llvm-readobj to verify that the correct alignment has been
applied to the .toc section.
Thanks to Ulrich Weigand for running down where the fix was needed.

Target/X86: Never use the redzone for Win64 ABI functions.
Summary:
Until now, we did this (among other things) based on whether or not the
target was Windows. This is clearly wrong, not just for Win64 ABI functions
on non-Windows, but for System V ABI functions on Windows, too. In this
change, we make this decision based on the ABI the calling convention
specifies instead.
