[SandboxIR][Tracker] Test UncondBrInst CondBrInst setters (#187549)
This checks the `setCondition()` and `setSuccessor()` setters introduced
in #187196.
[lldb] use the Py_REFCNT() macro instead of directly accessing member (#188161)
[PyObject members are not to be accessed
directly](https://docs.python.org/3/c-api/structures.html#c.PyObject),
but rather through macros, in this case `Py_REFCNT()`.
In most, ie Global Interpreter Lock-enabled, CPython cases,
`Py_REFCNT()` expands to accessing `ob_refcnt` anyway. However, in a
free-threaded CPython, combined with disabling the limited API (since it
requires the GIL for now), the direct member does not exist, causing the
build to fail. The macro expands to the correct access method in the
free-threaded configuration.
[libc++] Fix type confusion in hash_{,multi}map
The type `__gnu_cxx::hash_{,multi}map` creates objects of type
`std::pair<Key, Value>` and returns pointers to them of type
`std::pair<const Key, Value>`. If either `Key` or `Value` are
non-standard-layout, this is UB, and is furthermore considered by
pointer field protection to be a type confusion, which leads to a
program crash. Fix it by using the correct type for the pair's storage
and using const_cast to form a pointer to the key in the one place where
that is needed.

[mlir][mem2reg] Process direct uses inside other regions. (#188359)
We need to add the regions with the direct uses into the list
for processing, otherwise the direct uses will not be removed
and will use the slot after the promotion.
The added LIT test was triggering "after promotion, the slot pointer
should not be used anymore" assertion.
[lldb][DWARFASTParserClang] Handle pointer-to-member-data non-type template (#187598)
## Description
### Problem
MakeAPValue in DWARFASTParserClang.cpp did not handle
pointer-to-member-data non-type template parameters (e.g., template <int
S::*P>), causing LLDB to produce incorrect results or crash.
DWARF encodes pointer-to-member-data NTTPs as
`DW_TAG_template_value_parameter` with a `DW_AT_const_value`
representing the byte offset of the member within the containing struct.
MakeAPValue is responsible for converting this value into a clang
APValue, but it only handled integer/enum and floating-point types. For
pointer-to-member types, it returned `std::nullopt`.
This caused the caller (ParseTemplateDIE) to fall back to creating a
type-only TemplateArgument (kind=Type) instead of a value-carrying one.
When two specializations differ only by which member they point to

[BOLT] Support buildid in pre-aggregated profile (#186931)

[lldb] Mark lldbtest.build() parameters as keyword-only (#188327)
This reinforces what is already true in the codebase: all uses of

With this change, it will be an error to call `build` using positional
arguments:
```
TypeError: build() takes 1 positional argument but 2 were given

[llvm][SPIRV] Add pass to lower Ctors/Dtors for SPIRV (#187509)
This PR adds a new SPIRV pass that generates a kernel named
"spirv$device$init" that iterates the pointers in the table pointed by
__init_array_start and __init_array_end and executes them. It also
generates symbols for each constructor with the form
__init_array_object_NAME_PRIORITY.
These symbols will be used by the Level Zero plugin in the liboffload
runtime (with the support introduced by #187510) to generate the
aforementioned table as spirv-link cannot create the table itself.
It also does the same thing for destructors, with the kernel name being
"spirv$device$fini", the table pointers __fini_array_start and
__fini_array_end, and the generated symbols prefix __fini_array_object.
The code was mostly generated by Claude 4.5 and has been reviewed by me
to the best of my ability.

[InstallAPI] [Tests] Avoid checking compiler output for 'error' (#188307)
We have two tests that use FileCheck for diagnostics and which try to
check that the output contains no compiler errors by checking for the
string 'error'. The issue with this approach is that this also causes
those tests to fail if the *path* contains the word 'error', which can
happen e.g. if the branch name contains the word 'error'.
Instead, we now check for `error:` since that string is much less likely
to appear in a path.
