Without this patch 6 marshalling tests fail on Windows.
This patch contains the following changes:
- Allow paths with Windows slashes (convert to the POSIX style instead of assertion)
- Add support for URI with Windows path.
- Change the value of the second parameter of several `llvm::sys::path::convert_to_slash()` calls: we should use `windows` instead of `posix` to ensure UNIX slashes in the path.
- Port `RemoteMarshallingTest::IncludeHeaderURI` test to Windows.

D70365 allows us to make attributes default. This is a follow up to
actually make nosync, nofree and willreturn default. The approach we
chose, for now, is to opt-in to default attributes to avoid introducing
problems to target specific intrinsics. Intrinsics with default
attributes can be created using `DefaultAttrsIntrinsic` class.
This still satisfies the constraints required by the affine dialect and
gives more flexibility in what iteration bounds can be used when
loewring to the GPU dialect.

This allows removing the clangAST dependency from libclangToolingCore and
therefore allows clang-format to be built without depending on clangAST.
Before 1166 files had to be compiled for clang-format, now only 796.

Add a nul byte to the stream in CommunicationKDP::CheckForPacket
before we send the GetData() to a Log::Printf as a c-str. Avoids
a crash when logging kdp communications and memory layout isn't
in your favor.
This:
1) Changes the return type of `MappingTraits<T>>::validate` to `std::string`
instead of `StringRef`. It allows to create more complex error messages.
2) It introduces std::vector<std::pair<StringRef, bool>> getEntries():
a new virtual method of Section, which is the base class for all sections.
It returns names of special section specific keys (e.g. "Entries") and flags that
says if them exist in a YAML. The code in validate() uses this list of entries
descriptions to generalize validation.
This approach was discussed in the D89039 thread.

The "Size" value returned by SystemZDisassembler::getInstruction is
used by common code even in the case where the routine returns
failure. If that Size value exceeds the number of bytes remaining
in the section, that could cause disassembler crashes.
Fixed by never returning more than the number of bytes remaining.
This reverts commit 38f625d0d1.
This commit contains some holes in its logic and has been causing
issues since it was commited. The idea sounds OK but some cases were not
handled correctly. Instead of trying to fix that up later it is probably
simpler to revert it and work to reimplement it in a more reliable way.
The Value hierarchy consists of BlockArgument and OpResult, both of which
derive Value. Introduce IsA functions and functions specific to each class,
similarly to other class hierarchies. Also, introduce functions for
pointer-comparison of Block and Operation that are necessary for testing and
are generally useful.

This fixes miscomputation of __builtin_constant_evaluated in the
initializer of a variable that's not usable in constant expressions, but
is readable when constant-folding.
If evaluation of a constant initializer fails, we throw away the
evaluated result instead of keeping it as a non-constant-initializer
value for the variable, because it might not be a correct value.
To avoid regressions for initializers that are foldable but not formally
constant initializers, we now try constant-evaluating some globals in
C++ twice: once to check for a constant initializer (in an mode where
is_constannt_evaluated returns true) and again to determine the runtime
value if the initializer is not a constant initializer.
* Make cc1 and cc1as --compress-debug-sections an alias for --compress-debug-sections=zlib
* Make -gz an alias for -gz=zlib
The new behavior is consistent with GCC when binutils>=2.26 is detected:
-gz is translated to --compress-debug-sections=zlib instead of --compress-debug-sections.
* Interops with Python buffers/numpy arrays to create.
* Also cleans up 'get' factory methods on some types to be consistent.
* Adds mlirAttributeGetType() to C-API to facilitate error handling and other uses.
* Punts on a lot of features of the ElementsAttribute hierarchy for now.
* Does not yet support bool or string attributes.

Instead of framing the interface around whether the variable is an ICE
(which is only interesting in C++98), primarily track whether the
initializer is a constant initializer (which is interesting in all C++
language modes).
No functionality change intended.
IRCE has some overhead for runtime checks and in case number of iteration is small
the overhead can kill the benefit from optimizations.
This CL bases on BlockFrequencyInfo of pre-header and header to estimate the
number of loop iterations. If it is less than irce-min-estimated-iters we do not transform the loop.
Probably it is better to make more complex cost model but for simplicity it seems the be enough.
The usage of BFI is added only for new pass manager and tries to use it efficiently.

This is a step towards separating checking for a constant initializer

evaluation of a variable initializer (in which it returns false).
extract_vector_elt will turn type vxi1 into i8, which triggers the assertion fail.

Recently commit D78699 (commit 26cfb6e562), fixed clang's behavior with respect
to passing a union type through a register to correctly follow the ABI. However,
this is an ABI breaking change with earlier versions of the clang compiler, so we
should add an -fclang-abi-compat option to address this. Additionally, the PS4 ABI
requires the older behavior, so that is added as well.
This change adds a Ver11 value to the ClangABI enum that when it is set (or the
target is the PS4 triple), we skip the ABI fix introduced in D78699.

Update clang/lib/Lex to stop relying on a `MemoryBuffer*`, using the
`MemoryBufferRef` from `getBufferOrNone` since both locations had logic

change, since the logic was wrong (it checked for `nullptr`, which was
never returned by the old API), but if that was reachable the new
