After D72555 has been landed, `linalg.indexed_generic` also accepts ranked
tensor as input and output. Add a test for it.

This patch:
- enable frame pointer for AIX;
- update some of red zone comments;
- add/update testcases;
Differential Revision: https://reviews.llvm.org/D72454
The test got re-enabled after d54d71b67e landed.
However it seems that the order is still not deterministic as it
currently passes with -DLLVM_ENABLE_EXPENSIVE_CHECKS=OFF but randomly
fails with expensive checks ON.
Test that instcombine and early-cse can cooperate
to reduce sequences of select patterns that are not
composed of the same underlying instructions.
There's a bug in EarlyCSE (PR41083), and we can test
how much a possible fix (D74285) may affect optimization.
Summary:
This revision adds EDSC support for VectorOps to enable the creation of a `vector_matmul` declaratively. The `vector_matmul` is a simple configuration
of the `vector.contract` op that follows the StructuredOps abstraction.

We were checking for extra uses of the negated operand even
if we were not going to create it as part of this canonicalization.
This was showing up as a regression when we limit EarlyCSE as
proposed in D74285.

Summary:
The return address validation in D71372 will fail if the memory permissions can't be determined. Many embedded stubs either don't implement the qMemoryRegionInfo packet, or don't have memory permissions at all.
Remove the return from the if clause that calls GetLoadAddressPermissions, so this call failing doesn't cause the step out to abort. Instead, assume that the memory permission check doesn't apply to this type of target.

`vector' uses the keyword-and-predefine mode from gcc, while __vector is
reliably supported.
As a side effect, it also makes the code consistent in its usage of __vector.

The idea of failing the symbolization when the symbolizer bufer is too small
was incorrect. The symbolizer can be invoked for other frames that may fit into
the buffer and get symbolized.

LoopCacheAnalysis currently assumes the loop will be iterated over in
a forward direction. This patch addresses the issue by using the
absolute value of the stride when iterating backwards.
Note: this patch will treat negative and positive array access the
same, resulting in the same cost being calculated for single and
bi-directional access patterns. This should be improved in a
subsequent patch.

Summary:
Instead of hand-crafting an offset into the structure returned by
dlopen(3) to get at the link map, use the documented API. This is
described in dlinfo(3): by calling it with `RTLD_DI_LINKMAP`, the
dynamic linker ensures the right address is returned.

Look up the -arch flags to pass to the mig invocation from an
optionally-defined MIG_ARCHS variable. We can't use CMAKE_OSX_ARCHS
because the {i,tv,watch}OS builds don't use this mechanism to achieve
fat builds (they build each slice separately & then lipo them together).
This supercedes the mig -arch/-isysroot fix from
510758dae2.
Each function is with this compiled with the SystemZSubtarget initialized
from the functions attributes.

The idiom
for (auto i = n - n; i < n; i += 1)
was intended to automatically derive the type of i from n
(signed/unsigned int) and avoid the 'mixed signed/unsigned comparison'
warning. However, almost-always-auto was never used in the LLVM coding
style (although we used it in Polly for some time) and I did never
intended to use this idiom upstream.
PVS Studio may warns about this idiom as 'warning: both sides of
operator are equivalent [misc-redundant-expression]'.
Remove the use of auto and directly use unsigned.

This CL refactors EDSCs to layer them better and break unnecessary
dependencies. After this refactoring, the top-level EDSC target only
depends on IR but not on Dialects anymore and each dialect has its
own EDSC directory.
This simplifies the layering and breaks cyclic dependencies.
In particular, the declarative builder + folder are made explicit and
are now confined to Linalg.
As the refactoring occurred, certain classes and abstractions that were not
paying for themselves have been removed.

Non-AVX512BW targets failed to concatenate 256-bit shifts back to 512-bits (split during 512-bit shuffle lowering as they don't have v32i16/v64i8 types).
This reverts commit b54a8ec1bc.
The commit triggered debug invariance (different output with/without
-g). The patch seems to have exposed a pre-existing invariance problem
in GlobalOpt, which I'll write a bug report for.
This patch renames `__personality_routine` to `_Unwind_Personality_Fn`
in `unwind.h`. Both `unwind.h` from clang and GCC headers use this name
instead of `__personality_routine`. With this patch one is also able to
build libc++abi with libunwind support on Windows.

The current standard to llvm conversion pass lowers subview ops only if
dynamic offsets are provided. This commit extends the lowering with a
code path that uses the constant offset of the target memref for the
subview op lowering (see Example 3 of the subview op definition for an
example) if no dynamic offsets are provided.

As noted on PR44379, we didn't attempt to lower vector shuffles using bit rotations on XOP/AVX512F targets.
This patch lowers to uniform ISD:ROTL nodes - ROTR isn't supported by XOP and they are interchangeable for constant values anyway.
There might be cases where targets without ISD:ROTL support would benefit from this (expanding to SRL+SHL+OR), which I'll investigate in a future patch.
REAPPLIED rGe82e17d4d4ca after reversion at rG39eade73a567 - fixed offset matching in matchShuffleAsBitRotate.
