This change allows the SRC and DST of dma_start operations to be located in the
same memory space. This applies to both the Affine dialect and Memref dialect
versions of these Ops. The documention has been updated to reflect this by
explicitly stating overlapping memory locations are not supported (undefined
behavior).

This covers the extremely common case of replacing all uses of a Value
with a new op that is itself a user of the original Value.
This should also be a little bit more efficient than the
`SmallPtrSet<Operation *, 1>{op}` idiom that was being used before.

Do not rely on pass labels to detect if the pattern was already applied in the past (which allows for more some extra optimizations to avoid extra InsertOps and ExtractOps). Instead, check if these optimizations can be applied on-the-fly.
This also fixes a bug, where vector.insert and vector.extract ops sometimes disappeared in the middle of the pass because they get folded away, but the next application of the pattern expected them to be there.

Broadcast dimensions of a vector transfer op have no corresponding dimension in the mask vector. E.g., a 2-D TransferReadOp, where one dimension is a broadcast, can have a 1-D `mask` attribute.
This commit also adds a few additional transfer op integration tests for various combinations of broadcasts, masking, dim transposes, etc.

This patch begins to translate acc.enter_data operation to call to tgt runtime call.
It currently only translate create/copyin operands of memref type. This acts as a basis to add support
for FIR types in the Flang/OpenACC support. It follows more or less a similar path than clang
with `omp target enter data map` directives.
This patch is taking a different approach than D100678 and perform a translation to LLVM IR
and make use of the OpenMPIRBuilder instead of doing a conversion to the LLVMIR dialect.
OpenACC support in Flang will rely on the current OpenMP runtime where 1:1 lowering can be
applied. Some extension will be added where features are not available yet.
Big part of this code will be shared for other standalone data operations in the OpenACC
dialect such as acc.exit_data and acc.update.
It is likely that parts of the lowering can also be shared later with the ops for
standalone data directives in the OpenMP dialect when they are introduced.
This is an initial translation and it probably needs more work.

This factors out the pass timing code into a separate `TimingManager`
that can be plugged into the `PassManager` from the outside. Users are
able to provide their own implementation of this manager, and use it to
time additional code paths outside of the pass manager. Also allows for
multiple `PassManager`s to run and contribute to a single timing report.
More specifically, moves most of the existing infrastructure in
`Pass/PassTiming.cpp` into a new `Support/Timing.cpp` file and adds a
public interface in `Support/Timing.h`. The `PassTiming` instrumentation
becomes a wrapper around the new timing infrastructure which adapts the
instrumentation callbacks to the new timers.

First step in adding alignment as an attribute to MLIR global definitions. Alignment can be specified for global objects in LLVM IR. It can also be specified as a named attribute in the LLVMIR dialect of MLIR. However, this attribute has no standing and is discarded during translation from MLIR to LLVM IR. This patch does two things: First, it adds the attribute to the syntax of the llvm.mlir.global operation, and by doing this it also adds accessors and verifications. The syntax is "align=XX" (with XX being an integer), placed right after the value of the operation. Second, it allows transforming this operation to and from LLVM IR. It is checked whether the value is an integer power of 2.
