[mlir] Introduce bare ptr calling convention for MemRefs in LLVM dialect
Summary:
This patch introduces an alternative calling convention for
MemRef function arguments in LLVM dialect. It converts MemRef
function arguments to LLVM bare pointers to the MemRef element
type instead of creating a MemRef descriptor. Bare pointers are
then promoted to a MemRef descriptors at the beginning of the
function. This calling convention is only enabled with a flag.

[PATCH] D73727: [SLP] drop poison-generating flags for shuffle reduction ops (PR44536)
We may calculate reassociable math ops in arbitrary order when creating a shuffle reduction,
so there's no guarantee that things like 'nsw' hold on those intermediate values. Drop all
poison-generating flags for safety.
This change is limited to shuffle reductions because I don't think we have a problem in the
general case (where we intersect flags of each scalar op that goes into a vector op), but if
there's evidence of other cases being wrong, we can extend this fix to cover those cases.

[mlir][spirv] Convert linalg.generic for reduction to SPIR-V ops
This commit adds a pattern to lower linalg.generic for reduction
to spv.GroupNonUniform* ops. Right now this only supports integer
reduction on 1-D input memref. Shader entry point ABI is queried
to make sure that the input memref's shape matches the local
workgroup's invocation configuration. This makes sure that the
workload fits in one local workgroup so that we can leverage
SPIR-V group non-uniform operations.
linglg.generic is a structured op that preserves the right level
of information. It is easier to recognize reduction at this level
than performing analysis on loops.
This commit also exposes `getElementPtr` in SPIRVLowering.h given
that it's a generally useful utility function.

[llvm-readobj][test] - Cleanup testing of the --sections command line option.
We have the `ELF\sections.test` to test --sections.
`ELF\sections.test` uses precompiled objects, it has a bug (does not test -s alias properly).
Also, we test machine specific section types in `ELF\machine-specific-section-types.test`,
so we probably do not need to test `--sections` for a MIPS object in `ELF\sections.test`.
I think it is enough to test ELF32 and ELF64 (we do not test ELF64 in this test).
`Object/readobj-shared-object.test` also tests how llvm-readobj handles
`--sections`. It is location is wrong, it is not complete, it uses precompiled binaries
and it duplicates the `ELF\sections.test` partially (it tests both ELF32 and ELF64).
We have `ELF\readelf-s-alias.test` that tests the `-s` alias for `--sections` in llvm-readobj
and `-s` as an alias for `--symbols` in llvm-readelf.
There is no need to have a separate test for such things.
The test for the `-s` alias for `--sections` can be included into the `ELF\sections.test`.
And the test for `-s` for llvm-readelf is already included into `ELF\symbols.test`.

1) Removes `Object/readobj-shared-object.test`.
2) Removes `ELF\readelf-s-alias.test`

[GISel][KnownBits] Fix a bug where we could run out of stack space
One of the exit criteria of computeKnownBits is whether we reach the max
recursive call depth. Before this patch we would check that the
depth is exactly equal to max depth to exit.
Depth may get bigger than max depth if it gets passed to a different
GISelKnownBits object.
This may happen when say a generic part uses a GISelKnownBits object
with some max depth, but then we hit TL.computeKnownBitsForTargetInstr
which creates a new GISelKnownBits object with a different and smaller
depth. In that situation, when we hit the max depth check for the first
time in the target specific GISelKnownBits object, depth may already
be bigger than the current max depth. Hence we would continue to compute
the known bits, until we ran through the full depth of the chain of
computation or ran out of stack space.
For instance, let say we have
GISelKnownBits Info(/*MaxDepth*/ = 10);
Info.getKnownBits(Foo)
// 9 recursive calls to computeKnownBitsImpl.
// Then we hit a target specific instruction.
// The target specific GISelKnownBits does this:
GISelKnownBits TargetSpecificInfo(/*MaxDepth*/ = 6)
TargetSpecificInfo.computeKnownBitsImpl() // <-- next max depth checks would
// always return false.
This commit does not have any test case, none of the in-tree targets
use computeKnownBitsForTargetInstr.
