[Analysis][NFC] Use block numbers in BlockFrequencyInfo (#190669)
Block pointers are only stored while constructing the analysis, so the
value handle to catch erased blocks is no longer needed when using
stable block numbers.
[LoopFusion] Fix out-of-date LoopInfo being used during fusion (#189452)
This is fix for
[187902](https://github.com/llvm/llvm-project/issues/187902), where
`LoopInfo` is not in a valid state at the beginning of `ScalarEvolution::createSCEVIter`.
The reason for the bug is that, `mergeLatch()` is called at a place
where control flow and dominator trees have been updated but `LoopInfo`
has not completed the update yet. `mergeLatch()` calls into
`ScalarEvolution` that uses `LoopInfo`, where out-of-date `LoopInfo` would
result in crash or unpredictable results.
This patch moves `mergeLatch()` to the place where `LoopInfo` has
completed its update and hence is in a valid state.
[CAS] Harden validate() against on-disk corruption (#190634)
Fixes found by fuzzer:
OnDiskTrieRawHashMap:
- Bounds-check data slot offsets in TrieVerifier::visitSlot() before
calling getRecord(), preventing asData() assertion on out-of-bounds
trie entries.
- Validate subtrie headers (NumBits, bounds) before constructing
SubtrieHandle, preventing SEGV in getSlots() from corrupt NumBits.
- Validate arena bump pointer alignment, catching misaligned BumpPtr
that would crash store() with an alignment assertion.
- Fix comma operator bug in getOrCreateRoot() where the
compare_exchange_strong result was discarded, causing asSubtrie()
assertion when RootTrieOffset was corrupted to zero.
OnDiskGraphDB:
- Reject invalid (zero) ref offsets in validate callback, preventing
asData() assertion when corrupt data pool refs are resolved via

devel/samurai: Update to 1.3
* Use INSTALL_* helpers for binary and manpages instead cp which
project Makefile uses
* Define additional CFLAGS in port makefile rather than in a patch

[CAS] Add llvm-cas-fuzzer for ObjectStore::validate() (#190635)
Add a fuzzer that creates an on-disk CAS database, stores objects, then
corrupts the on-disk data files using fuzzer-provided bytes and calls
validate(). The goal is that validate() should either succeed or return
an error, never crash.
The fuzzer supports 6 corruption modes: byte-level mutations, file
truncation, appending garbage, zeroing ranges, standalone file
corruption, and combined mutations with continued CAS operations.

[lldb] Fix UUID thombstone Key (#190551)
This changes `DenseMapInfo<UUID>::getTombstoneKey()` to return a 1-byte
`{0xFF}` sentinel instead of the empty, default constructed UUID().
Returning the same key for the empty and tombstone value apparently
violates the `DenseMap` invariant.
[AMDGPU][UniformityAnalysis] Mark set_inactive and set_inactive_chain_arg as SourceOfDivergence (#190640)
`set_inactive` produces a result that varies per-lane based on the EXEC mask, even when both inputs are uniform.
devel/gnu-efi: Remove stripping of object files
Stripping removes all symbols from CRTs and breaks applications linked
against gnu-efi (everything builds, but resulting file is not a valid
PE executable due to the way objcopy operates.
