liba52: Build fixes for GCC 15.
Update configure test for return type of signal(2).
Restrict to C99. Uses "old-style function definitions", but also
restrict keyword.
[LoopVectorize] Fix nondeterminism in loop-vectorize (#200833)
The nondeterministic iteration over `AddrDefs` (SmallPtrSet) causes
nondeterministic output for the test case in this patch (reduced from a
C codebase). One of two different outputs is generated arbitrarily,
chosen roughly equally.
Between the two different outputs sometimes the instruction
`%3 = load i64, ptr %2, align 8`
has an associated cost of 4 and othertimes 9. The instruction is visited
twice in `setCostBasedWideningDecision` in the `AddrDefs` loop: once
directly as an element of `AddrDefs`, and the other time indirectly in
the lambda `UpdateMemOpUserCost` as a User of another `AddrDefs`
element. Each of those times `setWideningDecision` is called with a
different cost value; the final of the two calls sets the final value
(previous is overwritten). Because `AddrDefs` iteration is
nondeterministic, the order of those two calls to `setWideningDecision`
is also nondeterministic, hence we see two different costs arbitrarily
between runs.

[ObjectYAML] Make BBAddrMap encoder diagnostics format-neutral (#202524)
In preparation for sharing the yaml2obj BBAddrMap encoder with COFF.
1. Drop the now-dead `Section.Type == SHT_LLVM_BB_ADDR_MAP` guards (#146186).
2. Reword the two warnings that will move into the shared helper.
3. Fix a "PBOBBEntries" -> "PGOBBEntries" typo.

Pull driver core updates from Danilo Krummrich:
"Deferred probe:
- Fix race where deferred probe timeout work could be permanently
canceled by using mod_delayed_work()
- Fix missing jiffies conversion in deferred_probe_extend_timeout()
- Guard timeout extension with delayed_work_pending() to prevent
premature firing
- Use system_percpu_wq instead of the deprecated system_wq
- Update deferred_probe_timeout documentation
device:
- Replace direct struct device bitfield access (can_match, dma_iommu,
dma_skip_sync, dma_ops_bypass, state_synced, dma_coherent,
of_node_reused, offline, offline_disabled) with flag-based
accessors using bit operations
- Reject devices with unregistered buses
- Delete unused DEVICE_ATTR_PREALLOC()

[LoopInterchange] Reject inner-latch lcssa PHI feeding the exit condition (#202863)
In a multi-level nest, an lcssa PHI in the inner loop latch that feeds
the latch's exit condition can be left with a stale incoming block after
a subsequent interchange rewires the CFG, producing invalid IR. This
happened even when the outer latch had a single predecessor, where the
legality check returned early. Instead, reject the interchange when such
a PHI feeds the exit condition.

[DA] Add test for addrec can wrap in GCD MIV (NFC) (#203526)
This patch adds a test that should have been included in #186892. The
test demonstrates a case where the GCD MIV test would miss a dependency
if the presence of nsw flags were not checked.
[clang][bytecode] Add an `ExplicitThisParam` flag to `Function` (#203672)
We unfortunately have to check this for every function call, so don't
consult the decl every time here.
