[CodeGen] Declare command line options in TableGen
Move the cl::opts of TargetPassConfig.cpp and CodeGenPrepare.cpp into
CodeGenOptions.td, private to lib/CodeGen; other files will follow.
-enable-machine-outliner (cl::ValueOptional) and -regalloc
(RegisterPassParser) stay cl::opt.
CodeGenPrepare and its addressing-mode helpers hold
`const CodeGenOptions &Opts`; TargetPassConfig functions read
CodeGenOptions::Global. getCGPassBuilderOption() converts
std::optional<bool> members to the cl::boolOrDefault fields of the
public CGPassBuilderOption. -basic-block-section-match-infer, which was
not cl::Hidden, is now listed by -help-hidden only.

[CodeGen] Stop exporting cl::opts. NFC
AMDGPU reads -misched-prera-direction and -verify-misched, every
target's TTI reads -partial-unrolling-threshold through BasicTTIImpl.h,
and AsmPrinter reads -emit-bb-hash through extern declarations. Add
getters for them, move inline code that reads options (LiveIntervals,
MachinePipeliner, MIR2Vec) out of line, and let unittests use default
weights, so that the options can be file-local.

[CIR] Reject language address spaces in DirectToLLVM pointer conversion
Reject unlowered language address spaces in pointer types when bypassing TargetLowering. Guard pointer-producing lowerings, including generated patterns, so failed conversions report legalization failures instead of silently selecting address space zero or constructing invalid LLVM operations.

[CIR] Propagate initializer type adjustment failures
Reject initializers whose active members have no LLVM representation, including when an enclosing union's storage type is convertible. Propagate recursive adjustment failures before querying data layout or constructing LLVM operations.

mkimg: Add support for stream-optimized VMDK
FreeBSD VM/cloud images tend to be highly compressible: The generic VM
images compress roughly 3.5:1, and cloud images typically even more
since they have significant unused space in their virtual disks. This
generally doesn't matter for users who can download compressed release
images and extract them locally, but for EC2 in particular relying on
uncompressed image formats is painful: We now upload over 500 GB/week
to AWS.
This commit adds the "stream-optimized" version of the VMDK format,
which compresses each 64 kB "grain" individually (and omits grains
which are all zeroes). Compared to uncompressed formats, this can
produce much smaller images; experiments indicate that using this
format for EC2 image uploads will reduce the weekly traffic to under
100 GB/week.

__FreeBSD_version: Bump for mkimg -f vmdks
Also, adjust bootstrap tools code in Makefile.inc1 to reflect this; in
addition to rebuilding mkimg if it is out of date, we now need to build
libz, which was not previously needed by mkimg.

mkimg: Add image_buffer_region
This is like image_copyout_region, but copies into a buffer rather than
writing out to a file; it will be used by future support for compressed

[Clang] Keep scope annotations covering typo-corrected qualifiers (#223978)
Fixes #221890
While tentatively deciding whether `(void(foo::S<int>))` is a type-id,
the parser annotates `foo::S<int>`. Lookup of `S` in `foo` fails, typo
correction suggests plain `S`, and Sema rebuilds the `CXXScopeSpec`
without the qualifier. The annotation token takes its start from that
scope specifier, so it only covers `S<int>` and the already-consumed
`foo ::` tokens are never replaced in the token cache. They resurface
after the tentative parse backtracks, every later parse sees `foo ::
<type>`, and the second `isTypeIdInParens()` in
`ParseCXXAmbiguousParenExpression` contradicts the first.
The parser owns the invariant that an annotation replaces every token
consumed to produce it, so the fix lives in
`ParseOptionalCXXScopeSpecifier`. After each Sema call that can rewrite
the qualifier through typo correction, the scope specifier is re-ranged
over the tokens actually consumed. When the qualifier was dropped
entirely, the template-id annotation is extended back over those tokens
instead. Sema and the typo-correction recovery are untouched.
[RegAllocFast] Order partial defs before other defs (#222882)
```
%0:gr64_with_sub_8bit = COPY $rax
%0.sub_32bit, %1:gr32 = MULX32rr $ecx, implicit $edx
```
The partial def of %0 is live-through: it reads the rest of %0, so it
must avoid the registers the instruction reads ($ecx, $edx) and is meant
to be allocated before an ordinary def like %1, which may share a
register with a use. The comparator in findAndSortDefOperandIndexes,
from the 2020 rewrite c8757ff3aa7d ("RegAllocFast: Rewrite and
improve"), tests `getSubReg() == 0`, the inverse of the allocation
sites, so %1 is allocated first and takes $eax; %0 then misses its hint
$rax, lands in $rsi, and the copy from $rax stays.
Share one isLiveThroughDef predicate between the ordering and the
allocation. %0 now takes $rax, the copy is deleted, and %1 takes $ecx.
