[mlir][bufferization] Cache areNonConflictingSubsets results in OneShotAnalysis (#189895)
The `areNonConflictingSubsets` check in `hasReadAfterWriteInterference`
can be expensive when called repeatedly for the same (uRead,
uConflictingWrite) pairs during bufferization analysis. This patch
caches the results to avoid redundant computation.
Specifically, this adds:
- A private `nonConflictingSubsetCache` DenseMap on
`OneShotAnalysisState` to memoize subset conflict results.
- A public `areNonConflictingSubsetsCached` method that wraps the
lookup-or-compute pattern, following the same convention as the existing
`findDefinitionsCached`.
- Cache invalidation in `resetCache()`.

[lldb][AArch64][Linux] Fix memory tagging tests (#192421)
The test program was relying on mmap calls to allocate pages that were
next to each other, which is not guaranteed but I got away with it on
our simulated systems for a time.
Instead of taking this chance, allocate all the pages once and then
split the allocation by changing the permissions of each page. That
ordering we can rely on.
The repeating tag options test is broken due
to #192057 so I've xfailed it.
[libc] Implement getsockopt and setsockopt on linux (#192237)
This patch implements getsockopt and setsockopt socket functions on
Linux. It follows the established pattern of wrapping socketcall or
using direct syscalls.
I added a basic test setting a couple of options.
I only added the first couple of simple constants (e.g. whose value does
not depend on the architecture). I've left the others for a separate
patch.
[libc][test] Fix getcwd test for symlinked paths (#191426)
The test compared getcwd() with getenv("PWD"), which is not reliable
under symlinked paths: PWD may preserve the logical path while getcwd()
returns the physical path.
Use stat(2) to verify directory identity instead.
