[CIR][CodeGen][NFC] Extract the EHPersonality struct into CodeGenUtils (#223420)
Deduplicates the `EHPersonality` struct and its personality constants between
CIR and classic CodeGen into `EHPersonality.h`. The `EHPersonality::get`
factories become `getEHPersonality` overloads, since the shared struct cannot
name either CodeGenModule.

tests/sys/vfs: Fix the Linux kld check
linux and linux64 are file names, not module names. The corresponding
module names are linuxelf and linux64elf, respectively, so these tests
were always being skipped.

[hexagon] Add hexagon_hvx function attribute. (#223771)
- [x] Add hexagon_hvx function attribute to be used to annotate function
that contains hand written hvx instructions.
- [x] Add logic to prevent these functions being inlined into or inline
other functions that don't have the same attributes.
- [x] Add tests.
[clang][ASTMatchers] Share variadic dyn-cast matcher marshalling (#202941)
Replace the templated variadic dyn-cast matcher descriptor with one
implementation parameterized by base and derived AST node kinds, while
preserving the typed conversion and derived-kind restriction.
On arm64 Release builds, this reduces stripped `clang-query` by 721,456
bytes, the affected objects by 768,528 bytes, and object relocations by
9,495.

NVPTX: Drop LiveVariables from the register allocation pipeline
The optimized RegAlloc pipeline ran LiveVariables only to satisfy PHIElimination
and TwoAddressInstruction, both of which no longer need it. Remove the
LiveVariables run (and, in the new pass manager, the UnreachableMachineBlockElim
that was there only as a LiveVariables prerequisite).

vfs_bio: retry fresh buffer allocation if recycling fails
getnewbuf() uses buf_lotsfree() to choose whether to
allocate a fresh buffer before trying BQ_AGE and BQ_LRU.
If fresh allocation is skipped and no buffer can actually be
recycled, it sleeps on needbuffer_cv even when the buffer cache
is still below its high water mark.
In that situation, a thread which could release a buffer may
itself need another buffer, resulting in a deadlock.
To avoid this, if recycling finds no usable buffer and bufmem is
still below bufmem_hiwater, make one more PR_NOWAIT fresh allocation
attempt before sleeping. See PR kern/60584 for details.

atari: Fix fatal 68030 MMU TC initialization bug
ATARITT kernels from NetBSD 11.0 and -current fail to boot on my
Atari TT030.
The inline asm that loads TC specifies only `"a" (&tc)` as an input,
so the compiler may eliminate the initialization of tc as a dead store.
Then the generated code loads an uninitialized value from the stack
into TC.
Add an `"m" (tc)` input operand to the inline asm so that the compiler
knows that the asm reads tc from memory.

[flang] Associate named constant actual arguments with their storage (#222986)
Named constants (PARAMETER) used as actual arguments were folded to
anonymous values before call analysis, so a whole named array passed to
an explicit-shape dummy went through an unnecessary temporary, and an
array element could not start an element sequence association at all
(bogus "Whole scalar actual argument may not be associated with a dummy
argument array" errors). For OpenACC programs that place module
PARAMETERs in device memory with `!$acc declare copyin`, the temporary
also breaks `default(present)` lookups, because the call no longer
refers to the constant's storage.
Retain eligible named-constant designators (whole arrays and array
elements) through argument analysis so that argument association can use
the constant's storage.
Element sequence association with an array VALUE dummy is kept rejected
(with a "not yet" message) and will be addressed in the future PR.

Add retrieval of unary operator spelling and python bindings (#219983)
Adds handling for unary operators in clang_getCursorSpelling() and

property to retrieve the UnaryOperator of a cursor.
The changeset is modeled after a972a394afcb276abb3029d0f2753d4403e379c2,
which introduced similar features for binary operators.
