The `vldap1` and `vstl1` RCPC3 intrinsics introduced in standard library unconditionally use `AtomicI64`. This breaks builds on target that do not support 64-bit atomics, such as `aarch64-unknown-none` with `max-atomic-width` set to 0. This commit adds a `#[cfg(target_has_atomic = "64")]` guard to these intrinsics

mGCA: Validate const literal against expected type close: rust-lang#151625 close: rust-lang#150983 also fix: rust-lang#133966 (moved crashes test)

…etrochenkov Don't ICE on layout error in vtable computation Fixes rust-lang#152030. Note: I'm including a more general testcase that doesn't use the feature in the original report, but only reproduces with debuginfo disabled. Does it make sense to also include the original testcase?

…petrochenkov `proc_macro::bridge`: simplify `ExecutionStrategy` and `DispatcherTrait` Also includes another tiny cleanup (functions can only have one return type).

@JonathanBrouwer

…uwer Port #[rustc_test_marker] to the attribute parser Tracking issue: rust-lang#131229 Targets: Const is for normal tests (const test::TestDescAndFn is inserted before the test fn) Const/Static/Fn is for custom_test_framework's #[test_case] e.g. tests/ui/custom_test_frameworks/full.rs r? @JonathanBrouwer Again I left the use-sites as is since they are early uses.

DepGraphQuery: correctly skip adding edges with not-yet-added nodes Fixes rust-lang#142152. The current logic already skips some edges, so I'm not sure how critical it is to have *all* the edges recorded, the logic seems to only be used for debug dumping. Recording all edges requires supporting holes in the `LinkedGraph` data structure, to add nodes and edges out of order, rust-lang#151821 implements that at cost of complicating the data structure.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
