We had previously been using a different workaround for pretending that

on dependency parsing for build systems, as explained in [1].
This patch changes the workaround to use `#pragma GCC system_header`,
which shouldn't suffer from the same issue. Unfortunately, it is a lot
more verbose. The issue is that `#pragma GCC system_header` is ignored
when we are inside a source file, so we have to create a header just for

This commit should fix a heap-use-after-free bug that was caught by the

The issue is that we were reading memory from a second target into a
`SBData` object in Python, that was passed to lldb's internal
`ScriptedProcess::DoReadMemory` C++ method.
The ScriptedPythonInterface then extracts the underlying `DataExtractor`
from the `SBData` object, and is used to read the memory with the
appropriate address size and byte order.
Unfortunately, it seems that even though the DataExtractor object was
still valid, it pointed to invalid, possibly garbage-collected memory
from Python.
To mitigate this, the patch uses `SBData::SetDataWithOwnership` to copy
the pointed buffer to lldb's heap memory which prevents the
use-after-free error.

[InstCombine] don't automatically drop poison-generating flags in SimplifyVectorDemandedElts
I noticed this while reviewing the test diffs in D115460
(and so the diffs in that patch will be reduced if this one is applied first).
This is effectively a revert of
3436dc29239d ( https://reviews.llvm.org/rG3436dc29239d ) -
since that commit, we've made several enhancements, so the reasoning there is no longer
valid. Specifically, we added a poison value to IR, and we clarified the behavior of
undef/poison elements in a shuffle mask:
https://llvm.org/docs/LangRef.html#shufflevector-instruction
Alive2 seems to agree that the propagation of flags in the test diffs shown here are valid:

[PR52475] Ensure a correct chain in copies to/from hidden sret parameter
This patch fixes an issue during SelectionDAG construction. When the
target is unable to lower the function's return value, a hidden sret
parameter is created. It is initialized and copied to a stored variable
(DemoteRegister) with CopyToReg and is later fetched with
CopyFromReg. The bug is that the chains used for each copy are
inconsistent, and thus in rare cases the scheduler may issue them out of
order.
The fix is to ensure that the CopyFromReg uses the DAG root which is set
as the chain corresponding to the initial CopyToReg.
