[Clang][FIX] Fix type qualifiers on vector builtins (#160185)

2025-09-25T23:32:24+00:00

Summary:
These were not stripping qualifiers when using them to infer the types,
leading to errors when mixiing const and non-const.

[lld][WebAssembly] Fix check for exporting mutable globals (#160787)

2025-09-25T23:23:39+00:00

We were not actually checking whether the global in question was
actually mutable before reporting the error.

[clang][DebugInfo][NFC] Simplify CollectRecordLambdaFields (#160690)

2025-09-25T22:53:52+00:00

This patch creates a helper to retrieve the name from a lambda capture
and only calls `createFieldType` once.

This will simplify reviewing some upcoming changes in this function.

[LifetimeSafety] Implement support for lifetimebound attribute (#158489)

2025-09-25T22:44:24+00:00

Add support for `lifetimebound` attributes in the lifetime safety
analysis to track loans from function parameters to return values.

Implemented support for `lifetimebound` attributes on function
parameters

This change replaces the single `AssignOriginFact` with two separate
operations: `OriginFlowFact` and `KillOriginFact`. The key difference is
in semantics:

* Old `AssignOriginFact`: Replaced the destination origin's loans
entirely with the source origin's loans.
* New `OriginFlowFact`: Can now optionally merge the source origin's
loans to the destination's existing loans.
* New `KillOriginFact`: Clears all loans from an origin.

For function calls with `lifetimebound` parameters, we kill the the
return value' origin first then use `OriginFlowFact` to accumulate loans
from multiple parameters into the return value's origin - enabling
tracking multiple lifetimebound arguments.

- Added a new `LifetimeAnnotations.h/cpp` to provide helper functions
for inspecting and inferring lifetime annotations
- Moved several functions from `CheckExprLifetime.cpp` to the new file
to make them reusable

The `lifetimebound` attribute is a key mechanism for expressing lifetime
dependencies between function parameters and return values. This change
enables the lifetime safety analysis to properly track these
dependencies, allowing it to detect more potential dangling reference
issues.
