Existing since its prototype

* CI: trigger library tests builds, when building runtime tests

.. as they depend on it.

* Mono product build jobs only build the runtime, so don't trigger on library changes

* CI: Exclude some eng/pipelines files from triggering pipelines

```yml
    # src/workloads is only used in runtime-official builds
    # where evaluate-paths is not used
    _always_exclude: [
        eng/pipelines/common/evaluate-default-paths.yml

There is no need for this.

On ARM64, we turn the "EQ(CAST<byte>(x), 0)" into "TEST_EQ(x, 0xFF)",
to avoid materializing the cast.

However, this breaks recognition of the "cb[n]z" idiom. If "x" ends
up in a register, that's ok - we're essentially exchanging relop for a
cast. If, however, it was contained, it is better to leave it alone:

```
-            ldr     w0, [fp,#0x18]
-            tst     w0, #255
-            bne     G_M25131_IG10
-                                               ;; size=12 bbWeight=1    PerfScore 3.50
+            ldrb    w0, [fp,#0x18]
+            cbnz    w0, G_M25131_IG10
+                                               ;; size=8 bbWeight=1    PerfScore 3.00
```

We may get here for any invariant dividend/divisor but these can be
'complex' address-of trees that gtClone does not handle.

Fix #76051

* Delete IND<struct> handling from local morph

* Fix raw handle intrinsics

Also change it to check for any local, not just GT_LCL_VAR.

Under jit stress, `optOptimizeBoolsGcStress` will modify trees. Since this
now happens in a phase that runs after `fgSetBlockOrder`, it must also
rethread the trees.

Fixes build failures in official build. Tested locally

This was disabled by default in #76000. I started filling out the backport template when it hit me that we want to keep it here.

We'll want to backport these in tandem.

Better descriptions for why these tests are disabled.

* Fix Dictionary perf regression for non-string ref type keys

Several releases ago, some performance improvements were made to Dictionary that were particularly valuable for value type keys, enabling equality comparisons to be devirtualized and possibly inlined. For non-string reference type keys, however, this can end up being a regression, as every dictionary access then needs to access `EqualityComparer<TKey>.Default`, which can be more expensive with shared generics.  The access is hoisted out of a loop, but at least one per call is still needed.

This fixes the regression by ensuring we always store a comparer in the dictionary's constructor if TKey is a reference type.  The same fix is applied to `HashSet<T>`. This also means we can delete some now unreachable code.

* Address PR feedback

* Fix one more existing TODO

* Revert previous PR feedback changes

* Address PR feedback

`DiagnosticSource` is currently not AOT compatible. If a machine-wide DiagnosticSource-related event listener is enabled (such as PerfView, or possibly even a managed VS debugging session) it activates `DiagnosticSource` code paths within the executable and basically injects a runtime failure into NativeAOT processes due to the AOT-incompatibility of the code.

E.g. trying to do a `HttpClient` web request with PerfView collecting in the background causes a runtime exception to be thrown.

This uses the documented switch to disable `EventSource` support (unless the user specified a different value). Indirectly, it disables `DiagnosticSource` as well.

As a side effect, disabling `EventSource` drops the size of a NativeAOT-compiled Hello World from 3.48 MB to 2.85 MB 🥳.

* Ensure that frozen objects respect the minimum object size

* Handle FrozenStringNode too

Update `fgGetDomSpeculatively` to return nullptr if the idom of a block is
unreachable, even if other preds have refs.

Fixes #72767.

* Delete old jenkins scripts

* Improve handling of /p:CrossBuild=true

* Updated the Maui Perf net6.0 to get the latest daily 6.0 version.

* Setup for testing.

* Revert "Setup for testing."

This reverts commit 903014e269670595b05e08eca4d6de1b8edeab9f.

* Remove locks from COM events delegate management.

This removes locks and instead assumes the collection is immutable.

* Use array instead of List<T>

* Remove usage of `Delegate.Combine`. Upon deeper inspection there
doesn't seem to be any value to using that mechanism.

Use a bit vector to track the visited blocks. This scales much better than
using the per-block visited flags.

Fixes #44341.

In stress modes (and in normal uses, see test case) the jit may insert
patchpoint helper calls in regions where last error is live. So the helpers
need to preserve last error.

Because some invocations of the helpers may transition to OSR methods instead
of returning, we can't use the normal macros for this.

Fixes #75828.
