[AArch64] Change GeneratePerfectShuffle to return one destination operand for zip and transpose operations.

The tests added where crashing because zip instruction was returning two destination operands. ZIP according to arm returns only one destination operand.

This reverts commit 8bad4ae6.

Modifying AddRecs when constructing other expressions can lead to
surprising changes. It also seems like it is not really beneficial i
most cases.

At the moment, there's a single regression, but we still might be able
to improve the flags at AddRec construction.

Might help with the issue discussed in D143409.

Previously, we choose the median of three values. We now choose the median of
five values when the number of values being sorted exceed a threshold
(currently 100). This is similar to std::sort.

Change `dwim-print` to now disable persistent results by default, unless requested by
the user with the `--persistent-result` flag.

Ex:

```
(lldb) dwim-print 1 + 1
(int) 2
(lldb) dwim-print --persistent-result on -- 1 + 1
(int) $0 = 2
```

Users who wish to enable persistent results can make and use an alias that includes
`--persistent-result on`.

Since all callsites of `foreachTensorLoopId` would simply look up the `LatPointId` to extract its `BitVector`, it's cleaner to let the `Merger` handle that instead.  This seems to better capture the intent of the `foreachTensorLoopId` method, and improves decoupling (since it removes a place that leaks the implementation detail that we use `BitVector`).

Adds a basic logging class to Dexter that uses the existing PrettyOutput
class for printing and supports 3 levels of verbosity (note, warning,
error). Intended to consolidate the logging logic for Dexter into one
place, removing the need for conditional log statements and making it
easier for us later if we wish to use a more complete logging class.

By the psABI, any test case where a FPR would be used for a float, it
should also be used if you replaced that float with a _Float16. This
doesn't hold true in current Clang for the special cases in the FP
calling convention involving structs. This patch doesn't attempt to fix
that, simply to add coverage. D145074 contains the fix.

Note that getCleanShadow always returns Constant::getNullValue so the prior code is equivalent to convertToBool.

This is an implementation detail of the flattening scheme, so hide it in the implementation thereof.  This does require one caller to go through the appropriate utility, but doing that makes the code cleaner anyways.

This allows developing and distributing inlining heuristics

After D134050, it makes sense to combine the RV64 ABI tests into a
single file in order to make it more maintainable (i.e. not having to
split tests based on the combinations of ABIs they're expected to
impact). This patch deletes duplicated tests but doesn't do much further
reorganisation beyond that.

I imagine the logical ordering of tests in the file and comments could
be further improved in the future. My personal feeling is that it's
probably not worth investing the time to try to get this "perfect", and
to instead settle for this incremental step forward. But if there's
reviewer interest in attempting to further iterate, I'm happy to do so.

Having the header granularized makes it possible to remove the
dependency on this header in <format>. This <format> header gets
included in more headers due to more usage of std::formatter in the
