  clang-offload-bundler incorrectly errors on multi-CCOB binaries (#182579)

Issue: https://github.com/ROCm/llvm-project/issues/448

Objects can have multiple Clang Compressed Offload Bundles (CCOB) in the
.hip_fatbin section. This happens when there are multiple
translation/compilation units built and then linked together into an
Archive or Shared Object. The resulting .hip_fatbin section will have
multiple offload bundles delimited by the magic string "CCOB" (on a 4k
alignment boundary). The Clang Offload bundler API, when a List of
bundle entries is requested, was not properly iterating (looping) over
each separate bundle.

REPRODUCTION
Test File: librocblas.so.5 from ROCm 6.x distribution
.hip_fatbin section: 8,163,887 bytes containing 64 concatenated CCOBs

Extract the .hip_fatbin section with:
objcopy --dump-section .hip_fatbin=fatbin.bin binary

Structure:
Offset 0x0: CCOB header + 1.16 MB compressed (→ 12.41 MB uncompressed)
Offset 0x129000: CCOB header + 1.01 MB compressed (→ 13.14 MB
uncompressed)
Offset 0x227000: CCOB header + 36.5 KB compressed (→ 1.21 MB
uncompressed)
... (61 more bundles)

Command:
$ clang-offload-bundler --type=o --input=librocblas.so.5 --list

Error:
clang-offload-bundler: error: Failed to decompress input: Could not
decompress embedded file contents: Src size is incorrect

Expected:
Should list all target triples in the bundle, or at minimum process
the first bundle without error.

  [SLP] Enable widening strided revectorization of vector stores (#198920)

This commit adds support for re-vectorization of vector stores into
widened strided stores. That is:
```
%p1 = getelementptr i16, ptr %p0, i64 16
store <4 x i16> zeroinitializer, ptr %p1, align 2
store <4 x i16> zeroinitializer, ptr %p0, align 2
```
can be further vectorized to:
```
call void @llvm.experimental.vp.strided.store.v2i64.p0.i64(<2 x i64> zeroinitializer, ptr align 2 %p0, i64 32, <2 x i1> splat (i1 true), i32 2)
```

  [VPlan] Collect FOR PHIs before sinking/hoisting recurrence users (#194671)

Avoid iterating over HeaderVPBB->phis() while potentially mutating the
underlying VPBasicBlock. Collect all VPFirstOrderRecurrencePHIRecipe
instances first, then process them in a separate loop.

This prevents iterator invalidation when sinking or hoisting recurrence
users, and makes the transformation more robust.

  [LifetimeSafety] Fix false negative for GSL Owner methods inherited from a non-Owner base (#197864)

- Take the implicit object's actual type (e.g., the type before any
`DerivedToBase` cast) into account when checking for GSL Owner. Other
`isGslOwnerType` call sites with the same pattern (e.g.,
`isGslOwnerType(MCE->getImplicitObjectArgument()->getType())` in
`VisitCXXMemberCallExpr`) lack a real-world trigger today and are
deferred to a follow-up.
- Unify the GSL Owner checks inside `shouldTrackImplicitObjectArg` so
they share a single source of truth.

  [lit] Normalize RLIM_INFINITY to "infinity" in print_limits.py for Python 3.15+ (#190953)

Python 3.15 changed resource.getrlimit() to return the platform's
maximum value (e.g., 18446744073709551615 on 64-bit systems) instead of
-1 for RLIM_INFINITY. This breaks lit tests that expect -1 for unlimited
resource limits.

This patch normalizes the return value to "infinity" when it equals
RLIM_INFINITY to maintain compatibility with existing tests across all
Python versions.

Fixes test failure: shtest-ulimit-nondarwin.py
Expected: RLIMIT_FSIZE=-1
Got: RLIMIT_FSIZE=18446744073709551615

This reverts commit c76045d9bf3bd1c7a381dc85d1db63a38fd69aa4.

It does not look like this has been used anywhere since it was
implemented. I see no uses of it in LLVM, anywhere in our internal
monorepo, or across the entirety of Github outside of other copies of
LLVM tests. Given that, remove it. The intended use case around SSO ASan
string annotations is also likely to be significantly reworked soon.

  [InstrProf] Do not emit metadata for zero values with zero counts (#199380)

If we have a indirect call site with a profile that has VP information
for said callsite that only contains zero values with zero counts, we
would start to emit invalid profile information after
1d146967d51ba76b8379d9e12961aa23e5745701. VP metadata in this case is at
best redundant with BFI. So we restrict metadata emission to only if we
have a sufficient number of values for the VP metadata to be valid.
