[-Wunsafe-buffer-usage] NFC: Implement fix-strategies and variable-use-claiming.
This patch adds more abstractions that we'll need later for emitting
-Wunsafe-buffer-usage fixits. It doesn't emit any actual fixits,
so no change is observed behavior, but it introduces a way to emit fixits,
and existing tests now verify that the compiler still emits no fixits,
despite knowing how to do so.
The purpose of our code transformation analysis is to fix variable types
in the code from raw pointer types to C++ standard collection/view types.
The analysis has to decide on its own which specific type is
the most appropriate for every variable. This patch introduces
the Strategy class that maps variables to their most appropriate types.
In D137348 we've introduced the Gadget abstraction, which describes
a rigid AST pattern that the analysis "fully understands" and may need
to fix. Which specific fix is actually necessary for a given Gadget,
and whether it's necessary at all, and whether it's possible in the first place,
depends on the Strategy. So, this patch adds a virtual method which every
gadget can implement in order to teach the analysis how to fix that gadget:
Gadget->getFixits(Strategy)
However, even if the analysis knows how to fix every Gadget, doesn't
necessarily mean it can fix the variable. Some uses of the variable may have
never been covered by Gadgets, which corresponds to the situation that
the analysis doesn't fully understand how the variable is used. This patch
introduces a Tracker class that tracks all variable uses (i.e. DeclRefExprs)
in the function. Additionally, each Gadget now provides a new virtual method
Gadget->getClaimedVarUseSites()
that the Tracker can call to see which DeclRefExprs are "claimed" by the Gadget.
In order to fix the variable with a certain Strategy, the Tracker needs to
confirm that there are no unclaimed uses, and every Gadget has to provide
a fix for that Strategy.
This "conservative" behavior guarantees that fixes emitted by our analysis
are correct by construction. We can now be sure that the analysis won't
attempt to emit a fix if it doesn't understand the code. Later, as we implement
more getFixits() methods in individual Gadget classes, we'll start
progressively emitting more and more fixits.

This patch introduces a hierarchy of Gadget classes, which are going to be
the core concept in the somewhat sophisticated machine behind the upcoming

A gadget is a rigid code pattern that constitutes an operation that
the fixit machine "understands" well enough to work with. A gadget may be
"unsafe" (i.e., constitute a raw buffer access) or "safe" (constitute
a use of a pointer or array variable that isn't unsafe per se,
but may need fixing if the participating variable changes type
to a safe container/view).
We'll be able to make decisions about how to fix the code depending on
the set of gadgets that we've enumerated. Basically, in order to fix a type
of a variable, each use of that variable has to participate in a gadget,
and each such gadget has to consent to fixing itself according to
the variable's new type.

[clang-format] Don't require deduction guides to be templates
The C++ standard doesn't require that class template deduction guides
be templates themselves, but previously `isDeductionGuide` would assert
for the existence of a template closer or requires clause closer before
the deduction guide declaration.
This patch simply removes that check. Because of this, a test which
asserted that `x()->x<1>;` *isn't* a deduction guide failed, as it is
now formatted as a deduction guide. However, as @JohelEGP demonstrated,
it is [possible to make that a viable deduction guide][1].
Thus, that test has been removed, but other tests related to
non-template class template deduction guides have been added.

[mlir][tensor] Implement TilingInterface for unpack op
The main issue of tiling unpack op is about incomplete tile. Since all
the dimensions are orthogonal, discussing 1-d unpack case is enough. The
core idea is to make the input slice have complete tiles. In this case,
a larger unpacked tile will be created. We'll need an extract_slice op
to shift and truncate the output.
Take Nn_to_N as an example. Say that N=32, n=8, and tiling_size=15. The
coordinates of second tile (i.e., result[15..31]) are [(1, 7), (2, 0,),
(2, 1) ... (3, 6), (3, 7)]. The first row and the last row are
incomplete in terms of inputs. It's impossible to represent an unpack op
using the coordinates. Because the input has higher rank and the math
computation of coordinate is using mod and ceilDiv. That's very tricky.
To represent the unpack op, we have to complete the rows. I.e., the
input coordinates would start with (1, 0); end with (3, 7). In this
context, the tiled unpack produces a (3 * n) elements because there are
3 rows in total. Follow by a tensor.extract_slice op, we can get the
actual result.
If the tiling sizes are multiple of inner tile sizes, it is a perfect
tiling case. In this context, the larger input and output is not needed.
