[VPlan] Preserve branch weights from VPlan0 through to codegen. (#213143)
This patch adds support for carrying through branch weights from the
original scalar loop through VPlan.
The flow is as follows:
1. On the scalar VPlan, we import the branch weights from the existing
IR branches and add them as !prof metadata to VPInstruction terminators
2. The predicator dissolves the control flow and each block will get
executed unconditionally. What remains are predicated recipes, with
their lanes executing with probability relative to the header. Compute
the executing probabilities as sum of probabilities of all incoming
edges.
3. Each masked recipe gets the execution probability attached as custom
!vplan.execution.frequency metadata
4. When creating replicate regions, a predicated recipe is replaced by
explicit control fold. The execution frequency from the recipe is
converted to profile metadata and added to the newly introduced

[include-cleaner] Support Objective-C literals and boxed expressions in WalkAST (#216201)
This change adds AST visitors for ObjCBoxedExpr, ObjCArrayLiteral,
ObjCDictionaryLiteral, and ObjCStringLiteral. This ensures that the
underlying class interfaces (such as NSNumber, NSArray, NSDictionary,
and NSString) and any associated categories used for these literals are
correctly reported as referenced. Unit tests are included to verify the
new behavior.

rpi5: drop framebuffer_depth=32 from config.txt
The setting existed because the console runs on the firmware framebuffer,
where an unset depth yields 16bpp, bcm2835_fbd(4) then asks for 24, and the
console comes up dim and blue-cast. With VideoCoreKMS autoloading
(nextbsd-kernel-extensions#185) the intent is that KMS owns the display and
the firmware's depth stops mattering.
NOT VERIFIED ON HARDWARE. The Pi was unreachable when this was written, so
nobody has looked at a console without this line. Three things say it may
still be required, and they are recorded in the file rather than left for
someone to rediscover:
- the firmware allocates the console framebuffer before any kext can load,
so autoload does not change what happens at boot
- KMS does not take over the console. Measured with KMS loaded and
/dev/dri/card0 present:

ZIO: Batch vdev children completions
A vdev child ZIO's life after return from the block layer is three cheap
pipeline stages, yet each child costs its own taskq dispatch and context
switch to get there, only to decrement the parent's child count and die.
Even with increased number of taskqueues this can create a huge lock
contention and scheduler overheads, especially on large systems.
To avoid that extra cost collect the leaf children of a RAIDZ, dRAID or
mirror parents as they come back, and only once the last one is in,
process all of their completions, followed by the parent's one, all on
a single thread.
This optimization is mutually exclusive with I/O scheduler, since
delayed completions there may lead to a deadlock, but for that case I
have somewhat alike optimization idea later.
With this change my tests of 32KB block writes to 3x 5-wide NVMe RAIDZ1
on 64-core system show throughput increase from 13 GiB/s to 17 GiB/s,
