[mlir] Don't assume non-erased DenseMap entries remain valid after erase. NFC (#199365)
Like the preceding llvm/ change, fix MLIR sites that reuse an iterator
or bucket reference after erasing from the same map, in preparation for
backward-shift DenseMap deletion which relocates surviving entries.
Use DenseMap::remove_if in ThreadLocalCache::clearExpiredEntries and the
RootOrdering cycle contraction (deferring the in-cycle graph erases
until
after iteration). ThreadLocalCache::get reads the value into a local and
bufferizeOp snapshots the worklist before folding, since those erases
re-enter via a rewriter listener.

aarch64: mi pmap: save a PTE software bit when doing modify emulation.
Use only OS_MODEMUL and release OS_MODIFIED. A mapping is deemed modified
if it is marked RW and OS_MODEMUL which only ever happens via emulation.
mi pmap: pmap_clear_attribute should check cached value of the attribute
The pmap_clear_attribute implementation used by the MI pmap should
check the cached valued of the attribute as well as any value held
in the PTE(s).
Some emulation implementations require this as some operations, e.g
changing page mappings to RO, can lose PTE attribute information.

[orm] [bug]
Fixed issue where using joinedload() with PropComparator.of_type() targeting a joined-table subclass combined with PropComparator.and_() referencing a column on that subclass would generate invalid SQL, where the subclass column was not adapted to the subquery alias. Pull request courtesy Joaquin Hui Gomez.
[orm] [bug]
Fixed issue where the presence of a SessionEvents.do_orm_execute() event hook would cause internal execution options such as yield_per and loader-specific state from the first orm_pre_session_exec pass to leak into the second pass, leading to errors when using relationship loaders such as selectinload() and immediateload(). The execution options passed to the second compilation pass are now based on the original options plus only the explicit updates made via ORMExecuteState.update_execution_options() within the event hook.
[orm] [bug]
Fixed issue where using with_polymorphic() on a leaf class (a subclass with no further descendants) or a non-inherited class would fail with an AttributeError when used in an ORM statement, due to configure_mappers() not being triggered implicitly. The fix ensures that AliasedInsp participates in the _post_inspect hook, triggering mapper configuration during ORM statement compilation.

[AMDGPU] Implement "non-av" semantics using metadata
When the MMRA tag !{!"amdgcn-av", !"none"} is present on a synchronization
operation (fence, atomic load/store/rmw/cmpxchg), suppress cache writeback
(MakeAvailable) and cache invalidation (MakeVisible) while preserving
memory ordering (waits).
This implements the metadata proposed in #191246.
Fixes: LCOMPILER-2214

[AMDGPU] Refactor insertRelease into insertWriteback + insertWait (NFC)
A release consists of two actions: write-back the current cache, and wait for
"relevant" outstanding operations to complete. With the new memory model, it is
possible to disable the cache write-back using "av none" semantics. This patch
cleanly separates the existing implementation so that the write-backs can be
selectively applied when such metadata is present.
