Implement LWG 3629, by making lookup for make_error_code and
make_error_condition only consider names found by ADL. This is achieved
by adding a block scope using-declaration for a function that will be
found by unqualified lookup, preventing unqualified lookup from
continuing to enclosing scopes (the class scope, then enclosing
namespaces). The function named by the using declaration is not
viable, so overload resolution must select a candidate found by ADL.

In https://reviews.llvm.org/D133883, we changed the
`FoldExtractSliceIntoTransferRead` pattern from requiring
full identity map to minor identity map. This effectively
allows rank reducing `vector.transfer_read` ops. However,
the logic for checking `tensor.extract_slice` rank reducing
still looks at the vector rank, which now could be smaller
than the `tensor.extract_slice`'s output tensor rank.
It ends up we can have incorrect index cacluation after
folding due to this double rank reducing behavior.

When returning from a function with both SCS and PAC-RET enabled, we need to
authenticate the return address from the stack and then load from the SCS,
but this was happening in the reverse order when RETA[AB] were being used.
Fix it by disabling the use of RETA[AB] when SCS is enabled.

Fixes pr58072.

Now that all jobs have moved over to the new style of Lit configuration,
we can remove all traces of the legacy testing configuration system.
This includes:
- Cache settings that are not honored or useful anymore
- Several CMake options that were only useful in the context of the
  legacy Lit configuration system
- A bunch of Python support code that is not used anymore
- The legacy lit.cfg.in files themselves

   This will allow use GlobalVariable/Function as value.
2. Save target type for global ctors for Constant.

So we don't have to specify -enable-new-pm=0.

This fixes a crash when trying to access an index for a value where we
don't have a known index.

Fixes #58009.

The new pattern gets rid of the collapse_shape operation while
materializing its effects on the sizes, and the strides of the base
object.

In other words, this simplification replaces:

```
baseBuffer, offset, sizes, strides =
    extract_strided_metadata(collapse_shape(memref))
```

With

```
baseBuffer, offset, baseSizes, baseStrides =
    extract_strided_metadata(memref)
for reassDim in {0 .. collapseRank - 1}
  sizes#reassDim = product(baseSizes#i for i in group[reassDim])
  strides#reassDim = baseStrides[group[reassDim].back()]
```

Note: baseBuffer and offset are unaffected by the collapse_shape
operation.
