Tim Shen 3ccaac3cdd [mlir] Add MemRefTypeBuilder and refactor some MemRefType::get().
The refactored MemRefType::get() calls all intend to clone from another
memref type, with some modifications. In fact, some calls dropped memory space
during the cloning. Migrate them to the cloning API so that nothing gets
dropped if they are not explicitly listed.

It's close to NFC but not quite, as it helps with propagating memory spaces in
some places.

Alex Langford 381e81a048 [lldb][NFCI] Remove UserExpression::GetJITModule
UserExpression::GetJITModule was used to support an option in
UserExpression::Evaluate that let you hold onto the JIT Module used during
the expression evaluation. This was only actually used in one spot --
REPL::IOHandlerInputComplete. That method didn't actually take use the
JIT module it got back, so this feature was not used in practice.
This means that we can delete the support in UserExpression::Evaluate
and delete the UserExpression::GetJITModule method entirely.

Quentin Colombet cfebd77742 [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.

Pierre Habouzit bebb8e2596 [objc_direct] Small updates to help with adoption.
Add fixits for messaging self in MRR or using super, as the intent is
clear, and it turns out people do that a lot more than expected.

Allow for objc_direct_members on main interfaces, it's extremely useful
for internal only classes, and proves to be quite annoying for adoption.

Add some better warnings around properties direct/non-direct clashes (it
was done for methods but properties were a miss).

For non direct methods, the codegen uses the type of the Implementation.
Because Objective-C rules allow some differences between the Declaration
and Implementation return types, when the Implementation is in this
translation unit, the type of the Implementation should be preferred to
emit the Function over the Declaration.

Fangrui Song 5b22bcc2b7 [X86][ELF] Prefer to lower MC_GlobalAddress operands to .Lfoo$local
For a MC_GlobalAddress reference to a dso_local external GlobalValue with a definition, emit .Lfoo$local to avoid a relocation.

-fno-pic and -fpie can infer dso_local but -fpic cannot.  In the future,
we can explore the possibility of inferring dso_local with -fpic. As the
description of D73228 says, LLVM's existing IPO optimization behaviors
(like -fno-semantic-interposition) and a previous assembly behavior give
us enough license to be aggressive here.

Richard Smith 1f3f8c369a PR44721: Don't consider overloaded operators for built-in comparisons
when building a defaulted comparison.

As a convenient way of asking whether `x @ y` is valid and building it,
we previouly always performed overload resolution and built an
overloaded expression, which would both end up picking a builtin
operator candidate when given a non-overloadable type. But that's not
quite right, because it can result in our finding a user-declared
operator overload, which we should never do when applying operators
non-overloadable types.

Handle this more correctly: skip overload resolution when building
`x @ y` if the operands are not overloadable. But still perform overload
resolution (considering only builtin candidates) when checking validity,
as we don't have any other good way to ask whether a binary operator
expression would be valid.

//Code

```
struct foo {

...
foo my_foo = {10};
```

Trying to auto-complete my_foo.b with my_foo.bar resulted instead with my_foo.my_foo.bar

This diff fixes this bug and adds some tests to check correct behavior.

It also fixes the same bug using the arrow operator (->) when user manually requests completions.

Jonas Devlieghere 58c4fa2c53 [lldb/Reproducers] Use LLDB_RECORD_DUMMY for GetStopDescription
GetStopDescription writes to a const char* with a given length. However,
the reproducer instrumentation serialized the char pointer and length
separately.

To serialize the string, we naively look for the first null byte to
determine its length. This can lead to the method overwriting the input
buffer when the assumed string length is smaller than the actual number
of bytes written by GetStopDescription.

The real solution is to have a custom serializer that takes both
arguments into account. However, given that these are output parameters,
they don't affect replay. If the string is passed as input later, it's
is recorded as such. Therefore I've replaced the instrumentation macro
with LLDB_RECORD_DUMMY which skips the serialization.

Jessica Paquette c8c987d310 [AArch64][GlobalISel] Fold in G_ANYEXT/G_ZEXT into TB(N)Z
This is similar to the code in getTestBitOperand in AArch64ISelLowering. Instead
of implementing all of the TB(N)Z optimizations at once, this patch implements
the simplest case first. The way that this is set up should make it fairly easy
to add the rest as we go along.

The idea here is that after determining that we can use a TB(N)Z, we can
continue looking through instructions and perform further folding.

In this case, when we have a G_ZEXT or G_ANYEXT where the extended bits are not
used, we can fold it into the TB(N)Z.

which this CL adds.

Additionally, if doing a forced release, we'll release the
transfer batch class as well since now we can do that.

There is a couple of other house keeping changes as well:
- read the page size only once in the Secondary Cache `store`
- remove the interval check for `CanRelease`: we are going to
  make that configurable via `mallopt` so this needs not be
  set in stone there.
