[X86] LowerAndToBT - fold ICMP_ZERO(AND(X,AND(Y,SHL(1,Z)))) -> BT(AND(X,Y),Z) patterns (#182007)

[ASan/sanitizers] Make stack unwinding better on Windows. (#180205)
I created an issue about this in #179976.
Clang's Address Sanitizer installs its own SEH filter which handles some
types of uncaught exceptions. Along with register values and some other
information, it also generates a stack trace. However, current logic is
incomplete. It relies on DbgHelp's SymFunctionTableAccess64 and
SymGetModuleBase64 which won't work with machine code that has its
RUNTIME_FUNCTION entry registered with Rtl* (e.g. RtlAddFunctionTable)
system calls. Most likely, this is because DbgHelp either relies on
information in PDB files or considers PDATA and XDATA only from loaded
EXE and DLL modules. Either way, consider the following example:
```
#include <windows.h>
#include <iostream>
#include <vector>

libclc: Stop using r600 asm intrinsic declarations for amdgcn (#181975)
Really the workitem functions should all be moved to generic code
and use gpuintrin.h. These implementations were copied from there.
NAS-139852 / 26.0.0-BETA.1 / Expand test coverage for auth failures (#18234)
* Verify that we're generating proper audit message when user abandons a
2FA attempt.
* Verify that we're generating proper audit message and response when
user attempts to auth with expired API key.

[lldb][PlatformDarwin][NFCI] Factor out dSYM script auto-loading into helper function (#182002)
Depends on:
* https://github.com/llvm/llvm-project/pull/182001
(only second commit is relevant for this review)
This patch factors out the logic to load dSYM scripting resources into a
helper function. In the process we eliminate some redundant copying of
`FileSpec` and pass it to the helper by `const-ref` instead
(specifically the `symfile_spec`).
[SelectionDAG] Fix bug related to demanded bits/elts for BITCAST
When we have a BITCAST and the source type is a vector with smaller
elements compared to the destination type, then we need to demand
all the source elements that make up the demanded elts for the
result when doing recursive calls to SimplifyDemandedBits,
SimplifyDemandedVectorElts and SimplifyMultipleUseDemandedBits.
Problem is that those simplifications are allowed to turn non-demanded
elements of a vector into POISON, so unless we demand all source
elements that make up the result there is a risk that the result
would be more poisonous (even for demanded elts) after the
simplification.
The patch fixes some bugs in SimplifyMultipleUseDemandedBits and
SimplifyDemandedBits for situations when we did not consider the
problem described above. Now we make sure that we also demand vector
elements that "must not be turned into poison" even if those elements
correspond to bits that does not need to be defined according to
the DemandedBits mask.
