[clang][modules] Diagnose headers owned by multiple modules (#188538)
Add -Wduplicate-header-ownership, an off by default warning that fires
at include time when a header is owned by multiple top-level modules.
This helps catch overlapping module maps that can cause confusing module
resolution.

[NFC] Move TimePasses globals from Pass.h to PassTimingInfo.h (#192352)
They don't belong in the legacy pass manager-specific header, they apply
to both pass managers, plus the pass manager isn't the right layer to
put the bools anyway.
appleir: Add Apple IR receiver driver
HID driver for Apple IR receivers (USB HID, vendor 0x05ac).
Supports Apple Remote and generic IR remotes using NEC protocol.
Supported hardware:
- Apple IR Receiver (0x8240, 0x8241, 0x8242, 0x8243, 0x1440)
Apple Remote protocol (proprietary 5-byte HID reports):
- Key down/repeat/battery-low detection
- 17-key mapping with two-packet command support
- Synthesized key-up via 125ms callout timer
Generic IR remotes (NEC protocol):
- Format: [0x26][0x7f][0x80][code][~code]
- Checksum: code + ~code = 0xFF
- Default keymap with 8 common codes
- See: https://techdocs.altium.com/display/FPGA/NEC+Infrared+Transmission+Protocol

[CIR][ABI] Handle callee-destructed params for trivial_abi (#191257)
Replace errorNYI for isParamDestroyedInCallee with working
implementation: create aggregate temp, mark externally destructed,
emit expr. Unblocks [[trivial_abi]] types on Itanium ABI.
Adds trivial-abi.cpp test covering 17 cases from
CodeGenCXX/trivial_abi.cpp with CIR/LLVM/OGCG checks.

move-only types (trivial, default-ctor, move-ctor, etc.)
- x86_64-arguments.cpp — 26 functions covering C++ struct passing,
inheritance, member pointers, empty bases, packed structs

[CIR][NFC] Convert MissingFeatures::requiresCleanups to errorNYI (#192350)
This change adds errorNYI calls in two places that we previously had
requiresCleanups() missing features markers, adds a more specific
missing feature marker for loops, removes one requiresCleanups() where
the handling was already implemented, and deletes a bunch of missing
feature markers there were never used.
[BOLT][Passes] use ADT containers for instrumentation spanning tree. (#192289)
Swap `std::unordered_map<…, std::set<…>>` for
`DenseMap<…, SmallVector<…>>` in `Instrumentation::instrumentFunction`
and switch read paths from `STOutSet[&BB]` to `find()`. This removes
per-set heap allocations, stops inserting empty buckets on every probe,
and replaces linear `is_contained()` scans over a red-black tree with
linear scans over inline `SmallVector` storage (most basic blocks have
at most a couple of spanning-tree out-edges). NFC.

[CIR] Add address space casts for pointer arguments when creating a call (#192303)
This patch checks if the expected type for an argument is the same as
the actual type. If types are pointers but with different address spaces

Fix read corruption after block clone after truncate
When copy_file_range overwrites a recent truncation, subsequent reads
can incorrectly determine that it is read hole instead of reading the
cloned blocks.
This can happen when the following conditions are met:
- Truncate adds blkid to dn_free_ranges
- A new TXG is created
- copy_file_range calls dmu_brt_clone which override the block pointer
and set DB_NOFILL
- Subsequent read, given DB_NOFILL, hits dbuf_read_impl and
dbuf_read_hole
- dbuf_read_hole calls dnode_block_freed, which returns TRUE because the
truncated blkids are still in dn_free_ranges
This will not happen if the clone and truncate are in the same TXG,
because the block clone would update the current TXG's dn_free_ranges,
which is why this bug only triggers under high IO load (such as
