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.

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.

A constrained function with an auto return type would have it's definition
instantiated in order to deduce the auto return type before the constraints
are checked.
Move the constraints check after the return type deduction.
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.
In passing, split it up into three values (no explicit functions /
explicit conversion functions only / any explicit functions) in
preparation for using that in a future change.
This patch addresses the issue found in https://bugs.llvm.org/show_bug.cgi?id=44585
where a DW_OP_deref was placed at the end of a dwarf expression, resulting in corrupt
symbols when debugging.
This is an attempt to reland with a few fixes for buildbot since I

We can have geps that have a scalar base pointer, and a vector index value, which
means that the base pointer must be splatted into a vector of pointers.

Summary:
There was a bug on LLDB VSCode where there was the following behavior:
//Code
```
struct foo {
int bar:
};
...
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.

The CMakeLists.txt had a typo which meant that check-lldb-repro was
capturing twice instead of capturing and then replaying. This also
uncovered a missing import in lldb-repro.py. This patch fixes both
issues.
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.
I believe this also fixes bugs with CI 32-bit handling, which was
incorrectly skipping offsets that look like signed 32-bit values. Also
validate the offsets are dword aligned before folding.
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.

Found by inspection, but there's no test for this yet because G_PTR_ADD is
currently illegal for vectors. I'll add the test at a later time when the
legalizer support has landed.
This is never appropriate on Fuchsia and any future needs for
system library dependencies of compiler-supplied runtimes will
be addressed via .deplibs instead of driver hacks.

The test fix added by "D39306: Fix
CodeGen/AMDGPU/fcanonicalize-elimination.ll on FreeBSD 11.0" uses a test
prefix which is not actually used in the FileCheck stanza. Thus the
problem originally encountered still exists and the tests fails for host
triples that contain "1.0", including AIX 7.1.0.
This allows consumer to override in a cleaner way while still prevent
them from hitting bug without knowing they run an unsupported

There's not much value to this separate node from the intrinsic. Make
the operand structure the same as the intrinsic, so we can reuse the
same pattern for GlobalISel.
In line with current conventions, create new instructions rather
than modify two operands in place and performing manual worklist
management.
This should be NFC apart from possible worklist order changes.
Summary:
The Secondary's cache needs to be released when the Combined's
`releaseToOS` function is called (via `M_PURGE`) for example,
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.

Summary:
MLIR materializes various enumeration-based LLVM IR operands as enumeration
attributes using ODS. This requires bidirectional conversion between different
but very similar enums, currently hardcoded. Extend the ODS modeling of
LLVM-specific enumeration attributes to include the name of the corresponding
enum in the LLVM C++ API as well as the names of specific enumerants. Use this
new information to automatically generate the conversion functions between enum
attributes and LLVM API enums in the two-way conversion between the LLVM
dialect and LLVM IR proper.

When recording the result from the LLDB_RECORD_RESULT macro, we need to
update the boundary so we capture the copy constructor. However, when
called to record the this pointer of the (copy) constructor itself, the
boundary should not be toggled, because it is called from the
LLDB_RECORD_CONSTRUCTOR macro, which might be followed by other API
calls.
This manifested itself as an object encountered during replay that we
hadn't seen before. The index-to-object mapping would return a nullptr
and lldb would crash.
- Extends the comments related to function descriptors, noting how they
are only used on AIX.
- Changes the condition used to gate the creation of the current function
symbol in AsmPrinter::SetupMachineFunction to reflect being AIX
specific. The creation of the symbol is different because of AIXs
linkage conventions, not because AIX uses function descriptors.

Summary:
For -fpatchable-function-entry=N,0 -mbranch-protection=bti, after
9a24488cb6, we place the NOP sled after
the initial BTI.
```
.Lfunc_begin0:
bti c
nop
nop
.section __patchable_function_entries,"awo",@progbits,f,unique,0
.p2align 3
.xword .Lfunc_begin0
```
This patch adds a label after the initial BTI and changes the __patchable_function_entries entry to reference the label:
```
.Lfunc_begin0:
bti c
.Lpatch0:
nop
nop
.section __patchable_function_entries,"awo",@progbits,f,unique,0
.p2align 3
.xword .Lpatch0
```
This placement is compatible with the resolution in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92424 .
A local linkage function whose address is not taken does not need a BTI.
Placing the patch label after BTI has the advantage that code does not
need to differentiate whether the function has an initial BTI.
