This change provides `BufferizableOpInterface` implementations for ops from the Bufferization dialects. These ops are needed at the bufferization boundaries for partial bufferization.

This cmake configure option was added in
df0ba47c36, and was ported to
Bazel in 7d323dc773.
However, the setting chosen in Bazel seems accidental, not necessarily
intentional.
LLVM_WINDOWS_PREFER_FORWARD_SLASH has no effect on Unix, and on
Windows, setting it to 0 is the default, which gets the same behaviour
as before. Setting it to 1 enables new experimental behaviours
(which is enabled by default on MinGW targets only).
As I don't see any explicit intent to opt in to the new experimental
behaviour, I believe the current configuration in bazel was a
mistake.

This reverts commit 3028bca6a9.
For some reason using FallbackModel works with CMake and does not work
with bazel. Using `ExternalModel` works. I will check what's going on
and resubmit tomorrow.
Remove the interface from op defs in MemRefOps.td and make it an external model.
This is the first PR of many that will move bufferization-related ops, interfaces, passes to Dialect/Bufferize.

It is still debated if the comprehensive bufferization has to be moved there as well, so for now I am just moving the "gradual" bufferization.

This broke the Windows build:

Step towards removing the hard coded behavior for this trait and to instead use common interface.

This feature checks that headers included by a file are provided by a
header exported by one of the direct dependencies of the build rule in
which it is contained. It ensures that appropriate layering (a goal of
the LLVM project) is preserved. So far, I'm only adding this to MLIR
because we've had it turned on internally since the beginning, so MLIR
is already layering clean. It would be nice to also enable it for LLVM,
but that requires some additional cleanup.

We noticed that the library structure causes link ordering problems in Google's internal build. However, we don't think the problem is specific to Google's build, it probably can be reproduced anywhere with the right library structure.
In general splitting the Python bindings from their dependencies (the C API targets) creates the possibility that the two libraries might end up in the wrong order on the linker command line. We can avoid this problem happening by reverting the structure of the MLIRBindingsPythonCore to represent its dependencies in the usual way, rather than composing an incomplete `MLIRBindingsPythonCoreNoCAPI` target and their CAPI dependencies. It was probably a mistake to rewrite this particular `cc_library()` rule in terms of the two, since nothing guarantees that the two will be correctly ordered by the linker when both are being linked into the same binary, and it was only an incidental "cleanup" done in passing.
Otherwise the previous PR (D113565) is fine, since that was about the case where both are being built into two separate shared libraries. It just shouldn't have made this (unrelated) change.

This allows clients to build, e.g., the Python bindings against the C API headers, without including the C API implementations. This is useful when distributing software as multiple shared libraries.

Declarative attribute and type formats with assembly formats. Define an
`assemblyFormat` field in attribute and type defs with a `mnemonic` to
generate a parser and printer.
```tablegen
def MyAttr : AttrDef<MyDialect, "MyAttr"> {
let parameters = (ins "int64_t":$count, "AffineMap":$map);
let mnemonic = "my_attr";
let assemblyFormat = "`<` $count `,` $map `>`";
}
```
Use `struct` to define a comma-separated list of key-value pairs:
```tablegen
def MyType : TypeDef<MyDialect, "MyType"> {
let parameters = (ins "int":$one, "int":$two, "int":$three);
let mnemonic = "my_attr";
let assemblyFormat = "`<` $three `:` struct($one, $two) `>`";
}
```
Use `struct(*)` to capture all parameters.

This required substantially more invasive changes.
We need to handle some of the LLVM `config.h` changes differently from
the old pattern. These aren't always safe on the commandline, and the
Windows ones specifically break Clang. Instead, use conditional defines
in the header itself. This more closely matches how CMake builds see the
definitions. I think this is also just cleaner and we should maybe move
more of the macros out of Bazel.
The config defines for Windows that I've kept in Bazel are the ones that
LLVM's CMake does at the commandline as well. I've also added numerous
ones that CMake uses and we didn't replicate in Bazel.
I also needed a different approach to get `libclang` working well. This,
IMO, improves things on all platforms. Now we build the plugin and
actually wrap it back up with `cc_import`. We have to use a collection
of manually tagged `cc_binary` rules to get the naming to work out the
right way, but this isn't too different from the prior approach. By
directly having a `cc_binary` rule for each platform spelling of
`libclang`, we can actually extract the interface library from it and
correctly depend on it with `cc_import`. I think the result now is much
closer to the intent and to the CMake build for libclang.
Sadly, some tests also needed disabling. This is actually narrower than
what CMake does. The issue isn't indicative of anything serious -- the
test just assumes Unix-style paths.
I also have cleaned up the Windows flags in `.bazelrc` to much more
closely match what CMake does.

Sadly, these are necessary AFAICT. There is a file `lib/AST/CXXABI.h`.
On case insensitive file systems like macOS this will collide with
`cxxabi.h` on the system if we use the `includes` trick to allow
file-relative `#include` of generated files.
I've tested this on both Linux and Windows to make sure it remains
reasonably portable.
