clang: Add ArgRange builtin attribute for constant argument ranges
Many target builtins take constant arguments that must be in a
specific range. These usually correspond directly to the Range
annotation on the IR intrinsic, which the verifier enforces. Today
this requires manual verification with a large builtin ID switch in
Sema, and missed cases will emit code that fails the IR verifier.
Add an ArgRange<Index, Lo, Hi> builtin attribute declaring that a
_Constant argument must be in the half-open range [Lo, Hi), the same
as the IR declaration.

[ThinLTO] Run LowerTypeTests after indirect call promotion (#241582)
In ThinLTO backends, `LowerTypeTestsPass` ran before
`SampleProfileLoaderPass`
and `PGOIndirectCallPromotion`, renaming each CFI jump-table member
`foo` to
`foo.cfi` and leaving a `foo` declaration for the jump-table entry:
* `SampleProfileLoader` canonicalizes `foo.cfi` to `foo`, colliding with
the
`foo` declaration in `SymbolMap` and skipping sample annotation and ICP.
* Running ICP first lets it promote calls to `foo` under its original
name;
`LowerTypeTestsPass` then keeps direct calls to `foo.cfi` and redirects
the
promoted pointer comparison to `foo`.
Move `LowerTypeTestsPass` after ICP in
`buildModuleSimplificationPipeline`,

[ObjCARC] Treat objc_claimAutoreleasedReturnValue as RetainRV (#241436)
In spite of the names, claimRV really has much more in common with
retainRV than with unsafeClaimRV. Semantically claimRV is just retainRV
without the marker nop.
Currently GetFunctionClass doesn't handle claimRV at all, and it
defaults to CallOrUser. In well-behaved pass pipelines this omission
shouldn't be observable, but in the face of unusual pass ordering we
could have e.g. a situation where inlining happens after contraction,
and then the inliner gets confused and sends the claimRV down the
unsafeClaimRV +0 path, resulting in an over-release.
As a hardening against such situations, this patch classifies claimRV as
kind RetainRV. The additional changes in InlineFunction.cpp are just NFC
clarifications. Some of its mentions of "claimRV" are a bit too loose
when they actually mean unsafeClaimRV specifically.

[libc] Add CLOCK_TAI (#241692)
`CLOCK_TAI` is the kernel's clock for International Atomic Time, number
11. It was missing from the Linux time macros
AI disclosure: this patch was written with Claude Code. I reviewed the
change and built and ran the new test in a full build; it does not build
without the change

[libc][docs] Add search, filters, and drawers to dashboard (#241976)
With 82 headers on headers/index.html, finding a specific symbol or
inspecting which functions, macros, types, or global variables remain
unimplemented requires opening individual header pages one by one.
Add expandable detail drawers to each header row with category and
precision breakdowns plus clickable missing and implemented symbol chips
linked to cppreference.com and Open Group specifications, and add
client-side search, standard/status filtering, sorting, and
expand/collapse controls in status.js.

"To no surprise, this batch was mostly driven by issues found by LLMs

Fixes in GPIO core:
- fix a race in shared GPIO descriptor release path
- fix several issues in gpio-shared-proxy: race between concurrent
