[lldb] Use range-based for loops over plugins (#184837)
This PR replaces the Get*CallbackAtIndex pattern in the PluginManager
with returning a snapshot of callbacks that the caller can iterate over
using a range-based for loop. This is a continuation of #184452 which
added thread safety by using snapshots. However, that introduced a bunch
of unnecessary copies which are largely eliminated again by getting the
snapshot once when gather all the callbacks, rather than doing that on
each iteration when querying a plugin for a given index. It also
eliminates the possibility of the snapshot changing underneath you when
iterating over the plugins.
This change was largely mechanical and I used Claude to do the menial
work of updating the signatures and call sites.
[HWASan] add optimization remark for supported lifetimes
This lets us find functions where we pessimize codegen by removing
lifetimes.

[HLSL][Matrix] Make matrix truncation respect default matrix memory layout (#184280)
Fixes #183127 and #184371
This PR makes the matrix truncation cast implementation use the new
matrix flattened index helper functions introduced by #182904 so that it
reads elements from the source matrix using the default matrix memory
layout instead of always assuming column-major order.
This PR also fixes a bug where matrix truncation truncated the wrong
elements.

NAS-140179 / 27.0.0-BETA.1 / Introduce typed event source (#18396)
## Context
Introduce `TypedEventSource` which to the `run` body gives access to the
pydantic model itself which should be used so we can statically type
check properly arguments.

[CIR] Fix operator-precedence bugs in assert conditions
Due to && binding tighter than ||, asserts of the form
assert(A || B && "msg") always pass when A is true. Add
parentheses so the string message is properly attached:
assert((A || B) && "msg").
[AMDGPU][SIInsertWaitcnts][NFC] Simplify logic in GFX12Plus::applyPreexistingWaitcnts (#184925)
The loop is collecting the first instruction of each waitcnt kind and is
erasing the rest, with the exception of DEPCTR which needs more checks.
The existing code was factoring out the instruction deletion and the
setting of the collected instruction variables. But the special handling
for DEPCTR and the in-loop deletion of `S_WAITCNT_lds_direct` was just
complicating the logic.

[flang][cuda] Add hasManagedOrUnifedSymbols attribute to cuf.data_transfer op (#185106)
Add an attribute to signal the presence of managed or unified symbols in

insert synchronization. Adding the attribute in the op during lowering
facilitate the recognition of such data transfer.

[CIR] Change CmpOp assembly format to use bare keyword style
Update the assembly format of cir.cmp from the parenthesized style
cir.cmp(gt, %a, %b) : !s32i, !cir.bool
to the bare keyword style used by other CIR ops like cir.cast:
cir.cmp gt %a, %b : !s32i
The result type (!cir.bool) is now automatically inferred as it is
always cir::BoolType.
