[CodeGen] Declare command line options in TableGen (#228911)
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 BoolOrDefault
members to the cl::boolOrDefault and std::optional<bool> fields of the
public CGPassBuilderOption. -basic-block-section-match-infer, which was
not cl::Hidden, is now listed by -help-hidden only.

[Mips] Add microMIPS CP0 move encodings (#228884)
Define the microMIPS MFC0 and MTC0 formats and instruction records for
pre-R6 targets, including the select field. Accept the two-operand forms
with an implicit select value of zero and add generic scheduling
entries.
Extend the control-instruction tests with explicit and implicit select
operands, checking both byte orders.

[CodeGenPrepare] Prefix option names with cgp-
Rename the CodeGenPrepare options so that they start with cgp-, and turn
the -disable-* options into positive options that default to true:
```
-addr-sink-* -cgp-addr-sink-*
-cgpp-huge-func -cgp-huge-func
-disable-cgp-X -cgp-X=0
-disable-complex-addr-modes -cgp-complex-addr-modes=0
-disable-preheader-prot -cgp-preheader-prot=0
-enable-andcmp-sinking -cgp-andcmp-sinking
-force-split-store -cgp-force-split-store
-stress-cgp-X -cgp-stress-X
```
The section prefix options (-profile-guided-section-prefix, etc.) are
kept, as they are not specific to CodeGenPrepare.

[VPlan] Support pointer min/max bounds in VPlan memory runtime checks. (#225828)
Expand pointer-typed SCEV min/max expressions in VPSCEVExpander as
icmp + select (including profile metadata), matching SCEVExpander.
This allows modeling memory runtime checks with pointer min/max bounds
in VPlan, e.g. for accesses with a runtime stride of unknown sign.

rust199: fix build for powerpc by adding -mno-pltseq.
This is required due to the new gcc which comes along with NetBSD 10.0,
which is now the target for this rust build due to the requirement for
a newer gcc to build the embedded LLVM.
[mlir][acc] Declare the memory effects of acc.atomic.read
The operation read `x` and wrote `v` but declared no memory effects at
all, so every memory analysis had to treat both locations as unknown and
stay maximally conservative. In particular it could not be seen to
overwrite `v`.
Declare the effects per operand so the read on `x` and the write on `v`
are visible.
x11/plasma6-plasma-workspace: Fix build on older stable
On FreeBSD older than 1501503 the cameraindicator plugin is excluded
from the package, but it still gets installed into the stage directory.
ldd crashes on it during stage-qa and leaves ld-elf.so.1.core behind,
so check-plist fails. Remove the plugin from the stage directory as well.

www/{nginx,nginx-devel,freenginx}: 3rd-party modules management
Fix three defects in the body filter of the zstd module. A worker spins
at 100% CPU forever when an empty flush buffer arrives and the compressor
has nothing left to flush. A response is truncated at 131072 bytes when
a single input buffer larger than that carries last_buf. An output
buffer that is already full when ZSTD_endStream() is due gets dropped.
Upstream has not taken a code change since April 2024.

www/freenginx: Fix the packing list for the zstd module
The two entries were taken over from www/nginx and still named
libexec/nginx, while the port installs its modules into
libexec/freenginx. Building with ZSTD enabled failed in check-plist.
