This patch completes outstanding TODOs of removing aliases bazel target names.
This patch also renames and cosolidates some bazel targets to be more in line
with their CMake counterparts, e.g. combining `:LinalgOps` and `:LinalgInterfaces`
into `:LinalgDialect`.

Instead of crashing on a cast<FixedVectorType>, we should isntead return Invalid for these cases. This avoids crashes in assert builds, and potential miscompiles in release builds.
For an addition with simm14 and simm15 immediates with 2 or 3 trailing bits,
we can use a shXadd instruction and an addi to do the addition.
This patch teaches RISCVMergeBaseOffset to see through this pattern.
I don't think the sh1add case occurs because we use two addis for that,
but I implemented it for completeness.

This patch adds getFirstInstructionOffset method for BinaryFunction
which is used to properly handle cases where data is at zero offset in
a function. The main change is that we add basic block at first

Per the documentation in Support/InstructionCost.h, the purpose of an invalid cost is so that clients can change behavior on impossible to cost inputs. CodeMetrics was instead asserting that invalid costs never occurred.
On a target with an incomplete cost model - e.g. RISCV - this means that transformations would crash on (falsely) invalid constructs - e.g. scalable vectors. While we certainly should improve the cost model - and I plan to do so in the near future - we also shouldn't be crashing. This violates the explicitly stated purpose of an invalid InstructionCost.
I updated all of the "easy" consumers where bailouts were locally obvious. I plan to follow up with loop unroll in a following change.

As shown in D123408, we can produce this pattern when moving
cast around, and we already have a related fold for a binop
with a constant operand.
The linker can convert instructions with GOTPCRELX relocations into a
form that uses an absolute addressing with an immediate. BOLT needs to
recognize such conversions and symbolize the immediates.

Changes for GFX11:
- Clauses may not mix instructions of different types, and there are
more types. For example image instructions with and without a sampler
are now different types.
- The max size of a clause is explicitly documented as 63 instructions.
Previously it was implicitly assumed to be 64. This is such a tiny
difference that it does not seem worth making it conditional on the
subtarget.
- It can be beneficial to clause stores as well as loads.

It is sometimes better to make a copy of the OpResult instead of making a copy of the OpOperand. E.g., when bufferizing tensor.extract_slice.
This implementation will eventually make parts of extract_slice's `bufferize` implementation obsolete (and simplify it). It will only need to handle in-place OpOperands.

The TensorCopyInsertion pass resolves out-of-place bufferization decisions by inserting explicit `bufferization.alloc_tensor` ops. This change moves that functionality into a new BufferizableOpInterface method, so that it can be overridden by op implementations. Some op bufferizations must insert additional `alloc_tensor` ops to make sure that certain aliasing invariants are not violated (e.g., scf::ForOp). This will be addressed in a subsequent change.

Fixed issue with vector.contract default unroll permutation.
Adds support for vector unroll transformations to unroll in different
orders. For example, the vector.contract can be unrolled into a
smaller set of contractions. There is a choice of how to unroll the
decomposition based on the traversal order of (dim0, dim1, dim2).
The choice of traversal order can now be specified by a callback which
given by the caller of the transform. For now, only the
vector.contract, vector.transfer_read/transfer_write operations
support the callback.

Some object files produced by Mirosoft tools contain sections whose name field
is not fully null-padded at the end. Microsoft's dumpbin is able to print the
section name correctly, but this causes parsing errors with LLVM tools.
So far, this issue only seems to happen when the section name is longer than 8
bytes. In this case, the section name field contains a slash (/) followed by the
offset into the string table, but the name field is not fully null-padded at the
end.

This pass runs the One-Shot Analysis to find out which tensor OpOperands must bufferize out-of-place. It then rewrites those tensor OpOperands to explicit allocations with a copy in the form of `bufferization.alloc_tensor`. The resulting IR can then be bufferized without having to care about read-after-write conflicts.
This change makes it possible to connect One-Shot Analysis to other bufferizations such as the sparse compiler.

There are differences in handling of stat64/statfs64 calls by sanitizers between Linux and macOS. Versions of macOS starting with 10.6 drop the stat64/statfs64 APIs completely, relying on the linker to redirect stat/statfs to the appropriate 64 bit versions. Emitting variables needed by sanitizers is thus controlled by convoluted sets of conditions, involving Linux, IOS, macOS and Android, sprinkled around files.
This change adresses it, allowing to specify presence/absence of stat64/statfs64 for each platform, in a single location. Also, it adresses the Android case which handles stat64, but not statfs64.
Adding Vitaly as a reviewer since he seems to be actively working on sanitizers, perhaps can comment on the Android bit

PE/COFF can use either MSVC or GNU (MinGW) ABI for C++ code, however
LLDB had defaulted to MSVC implicitly with no way to override it. This
causes issues when debugging modules built with the GNU ABI, sometimes
even crashes.
This changes the PE/COFF plugin to set the module triple according to
the default target triple used to build LLDB. If the default target
triple is Windows and a valid environment is specified, then this
environment will be used for the module spec. This not only works for
MSVC and GNU, but also other environments.
A new setting, `plugin.object-file.pe-coff.abi`, has been added to
allow overriding this default ABI.

UNIX03 conformance requires utilities to flush stdout before exiting and raise
an error if writing fails. Flushing already happens on a call to exit
and thus automatically on a return from main. Write failure is then
detected by LLVM's default SIGPIPE handler. The handler already exits with
a non-zero code, but conformance additionally requires an error message.
First reapply attempt I hadn't noticed the test had changed, hopefully this
goes better.
