[Codegen, X86] Add prefetch insertion based on Propeller profile (#166324)
This PR implements the prefetch insertion in the InsertCodePrefetch pass
based on the
[RFC](https://discourse.llvm.org/t/rfc-code-prefetch-insertion/88668).
If the prefetch target is not defined in the same module (i.e, prefetch
target function is not defined in the same module), we emit a fallback
weak symbol after the prefetch instruction so that if the symbol is not
ever defined, we don't get undefined symbol error and the prefetch
instruction prefetches the next address:
```
prefetchit1 __llvm_prefetch_target_foo(%rip)
.weak __llvm_prefetch_target_foo
__llvm_prefetch_target_foo:
```
The weak symbol semantic is tied to ELF, so this makes this PR
target-dependent.
[SystemZ][z/OS] Show instruction encoding in HLASM output
This change adds the support to show instruction encoding as a comment
when emitting HLASM text. With this, the last 2 LIT tests migrate to
HLASM syntax.
games/xonix: Resurrect
This game has been deleted about a decade ago since the distfile
disappeared. Haolin Xue convinced me to resurrect it, and give
it a home at Github. They submitted a bunch of modernization
and security patches, so this is a new version now as well.
[clang-doc] Removed OwnedPtr alias
The alias served a purpose during migration, but now conveys the wrong
semantics, as the memory of these pointers is generally interned inside
a local arena.
[clang-doc] Use distinct APIs for fixed arena allocation sites
Typically, code either always emits data into the TransientArena or the
PersistentArena. Use more explicit APIs to convey the intent directly
instead of relying on parameters or defaults.
[clang-doc] Update type aliases
Many of the type aliases we introduced to simplify migration to arena
allocation are no longer relevant after completing the migration. We
can use more relevant names and remove dead aliases.
[clang-doc] Merge data into persistent memory (#190056)
We have a need for persistent memory for the final info. Since each
group processes a single USR at a time, every USR is only ever processed
by a single thread from the thread pool. This means that we can keep per
thread persistent storage for all the info. There is significant
duplicated data between all the serialized records, so we can just merge
the final/unique items into the persistent arena, and clear out the
scratch/transient arena as we process each record in the bitcode.
The patch adds some APIs to help with managing the data, merging, and
allocation of data in the correct arena. It also safely merges and deep
copies data from the transient arenas into persistent storage that is
never reset until the program completes.
This patch reduces memory by another % over the previous patches,
bringing the total savings over the baseline to 57%. Runtime performance
and benchmarks stay mostly flat with modest improvements.

[flang][OpenMP] Use common utility functions to get affected nest depth (#191418)
Remove the existing code that calculates the number of affected loops in
an OpenMP construct. There is a single function that does that and that
handles all directives and clauses.

NAS-140050 / 26.0.0-BETA.2 / Remove ips/interfaces fields from tnc configuration (#18666)
This PR adds changes to remove ips/interfaces field from TNC
configuration. These fields were earlier used to determine what IPs
should the TNC domain resolve to. Moving on, we have simplified the
implementation and now instead of asking the user - we rely instead on
`system.general.config` instead where ipv4/ipv6 values determine what
IPs TNC domain name resolves to. In case we have wildcard set in
`system.general.config` for ipv4/ipv6, for that specific protocol we get
all available IPs.
