[LifetimeSafety] Fix loop liveness leakage for conditional operator

Generate flow facts for conditional operators in their respective
predecessor blocks (branches) instead of the merge block, path-isolating
the flows and preventing liveness from leaking across loop backedges.

Also includes tests, formatting cleanups, and refactoring of the flow propagation.

[IR][NFC] Introduce Constant::containsMatchingVectorElement and corresponding matcher (#200502)

A common pattern when dealing with vectors is to iterate over each
element and check whether any element satisfies a condition. Introduce
`Constant::containsMatchingVectorElement` to generalize this behavior
along with a corresponding matcher `m_ContainsMatchingVectorElement`
which checks whether any elements match the given subpattern.

Remove function `llvm::maskContainsAllOneOrUndef` in favor of using this
generalization instead.

The original runtime verification only multiplied static output
dimensions per reassociation group and checked `srcDim % staticProduct`

The new verification uses getMixedOutputShape() to get all output
dimensions (static and dynamic), computes their product, and asserts
`product == srcDim`. Fixes #205981.

[lldb][driver] Fix ELF interposition of HostInfoBase symbols causing segfault (#204710)

Commit 67e571d (#179306) added lldbHost and lldbUtility to
`LLDB_DRIVER_LINK_LIBS` A side-effect is that HostInfoBase.cpp, which
contains the file-static `g_fields` pointer, is now compiled into both
the lldb binary and liblldb.so, giving each its own independent
`g_fields`.

On ELF platforms this creates an interposition hazard. When
`LLDB_ENABLE_DYNAMIC_SCRIPTINTERPRETERS` is set, AddLLDB.cmake switches
all LLDB libraries to `CXX_VISIBILITY_PRESET=default` so that the
version script can re-export private symbols needed by dynamically
loaded plugins. The Python plugin calls `HostInfo::GetShlibDir()`
directly, so extract-dynamic-script-interpreter-exports.py adds
`HostInfoBase::GetShlibDir` to liblldb.so's exports (global: in the
version script). `HostInfoBase::Initialize()` is not called by the
plugin and stays local:.

At runtime the dynamic linker resolves liblldb.so's PLT entry for
