Upon further investigation and discussion,
this is actually the opposite direction from what we should be taking,
and this direction wouldn't solve the motivational problem anyway.
Additionally, some more (polly) tests have escaped being updated.
So, let's just take a step back here.
This reverts commit f3190dedee.
This reverts commit 749581d21f.
This reverts commit f3df87d57e.
This reverts commit ab1dbcecd6.
- `[[format(archetype, fmt-idx, ellipsis)]]` specifies that a function accepts a
format string and arguments according to `archetype`. This is how Clang
type-checks `printf` arguments based on the format string.
- Clang has a `-Wformat-nonliteral` warning that is triggered when a function
with the `format` attribute is called with a format string that is not
inspectable because it isn't constant. This warning is suppressed if the
caller has the `format` attribute itself and the format argument to the callee
is the caller's own format parameter.
- When using the `format` attribute on a block, Clang wouldn't recognize its
format parameter when calling another function with the format attribute. This
would cause unsuppressed -Wformat-nonliteral warnings for no supported reason.

The dump of all diagnostics of all tests under `clang/test/{CXX,SemaCXX,SemaTemplate}` was analyzed , and all the cases where there were obviously bad canonical types being printed, like `type-parameter-*-*` and `<overloaded function type>` were identified. Also a small amount of cases of missing sugar were analyzed.
This patch then spells those explicitly in the test expectations, as preparatory work for future fixes for these problems.

A resolution to the ambiguity issues created by P0522, which is a DR solving
CWG 150, did not come as expected, so we are just going to accept the change,
and watch how users digest it.
For now we deprecate the flag with a warning, and make it on by default.
We don't remove the flag completely in order to give users a chance to
work around any problems by disabling it.

There's precedent for that in `CreateOr()`/`CreateAnd()`.
The motivation here is to avoid bloating the run-time check's IR
in `SCEVExpander::generateOverflowCheck()`.

When reaching the end of a function body, we need to ensure that the
ExitFunctionBodyRAII object is destroyed before we pop the declaration context
for the function. Exiting the function body causes us to handle immediate
invocations, which involves template transformations that need to know the
correct type for this.
This addresses PR48235.
We can reuse the "adjustment" handling logic in the higher level
of the solver by calling `State->assume`.

While we could emit such a tautological `select`,
it will stick around until the next instsimplify invocation,
which may happen after we count the cost of this redundant `select`.
Which is precisely what happens with loop vectorization legality checks,
and that artificially increases the cost of said checks,
which is bad.
There is prior art for this in `IRBuilderBase::CreateAnd()`/`IRBuilderBase::CreateOr()`.

Initiate the reorganization of the equality information during symbol
simplification. E.g., if we bump into `c + 1 == 0` during simplification
then we'd like to express that `c == -1`. It makes sense to do this only
with `SymIntExpr`s.

This change introduces subtarget features to predicate certain
instructions and system registers that are available only on
'A' profile targets. Those features are not present when
targeting a generic CPU, which is the default processor.
In other words the generic CPU now means the intersection of
'A' and 'R' profiles. To maintain backwards compatibility we
enable the features that correspond to -march=armv8-a when the
architecture is not explicitly specified on the command line.
