…es instead of aborting the trace (#107323)

Better diagnostic output when jiterp hits an invalid opcode

* Fix getting SSP for threadabort in funceval

Diagnostics test that test threadabort during funceval crashes on
machines with CET enabled. The reason is that when a thread is
redirected to the RedirectForThrowControl, the original instruction
address from which we've redirected is not on the shadow stack.
That causes the exception handling propagating the related
thread abort to fail finding that instruction address on the shadow
stack. It walks out of its range and then crashes with access
violation.

This change fixes it by storing the SSP in the FaultingExceptionFrame
and copying it to the REGDISPLAY when UpdateRegDisplay is called on
that frame. That way the correct SSP is already known in the SfiInit and
we don't need to look it up.

There is no logical distinction between creating a `DomainAssembly` and an `Assembly` now.

…in ilc.exe for native aot (#106716)

- Put copy of attributetesting.il test into the managed type system unit test suite

…(#107366)

There is a problem with the variant of the stack overflow test that can
overflow in a native function on ARM. The EHABI unwind info is not
present for leaf functions and libunwind is unable to unwind from the
failure location to the first managed frame.

I've created an issue (#107184) for the underlying problem. This PR
disables that test variant until the problem is fixed.

Close #106742

* Fix stack overflow reporting with multiple PALs

A recently reported issue in the stack overflow test running with
superpmi collect has revealed that there is a problem when multiple
shared libraries using coreclr PAL are loaded into the process.
Each such library registers signal handlers, including the SIGSEGV
one. The unexpected thing in the SIGSEGV handler in this scenario
is the fact that the GetCurrentPalThread() returns NULL in the
non-coreclr shared libraries in case the library didn't invoke
any function that would create the thread object.
That leads to the handler just writing "Stack overflow." to
the console and then calling PROCAbort(). This abort causes the process
to be torn down without reporting the stack overflow with full stack
trace by the coreclr.

This change fixes it by calling the previous registered handler instead
aborting in this case. That gives the coreclr SIGSEGV handler a chance to
do the reporting as expected.

we see the assert in GCHeap::GetHeap when called by wait_for_gc_done -

GCHeap* GCHeap::GetHeap (int n)
{
    assert (n < gc_heap::n_heaps);
    return gc_heap::g_heaps[n]->vm_heap;
}

when HC change is in progress and we are reducing the HC. this assert is actually unnecessary when called by wait_for_gc_done but is necessary when called by other methods like balance_heaps (those are in coop mode so they cannot observe the HC transition). so I just changed to getting the heap from g_heaps instead of calling GetHeap.

previously I thought this could actually be a functional problem but after doing more thinking I think this is just a benign assert. if we are observing the transition from the old HC to the new HC in wait_for_gc_done and we happen to be waiting on a heap that's decommissioned, decommission_heap sets its heap's gc_done_event so what will happen is wait_for_gc_done will wake up from waiting as soon decommission_heap is executed. at this time n_heaps is also updated. so when it gets to the next iteration in the while loop it will get a valid heap's gc_done_event to wait on.

The test added in #106787 found an issue in the implementation of reflection calls to array `Set` methods. We used to throw the wrong exception type.

Make the association between the wasm_native_to_interp_ftndescs generation and the lookup from unmanaged more robust so that we don't see problems like #107212 where the same slot was being reused for multiple methods with different signatures. To do this we change the Key(s) we use and fix the string escaping it relies on, and attempt to lookup by token first.

Next , we rewrite the C code generation to make it easier to read and modify and mitigate some potentially negative memory side effects of that we introduce a gratuitous custom text writer that understands the idea of concatenated strings and use that where possible when building the output.

Next, we change the import code generation to use binary rather than linear search for both the module and symbol. And finally, we update the ICall table generation to use the extensions.

The problem was that when we optimize `typeof(Foo) == somevalue` checks, we were looking at the presence of a constructed `MethodTable` of `Foo` in the whole program view. If it didn't exist, we'd declare the equality comparison can't succeed. There is however an edge case where someone could obtain a `System.Type` representing a type by browsing the reflection metadata. Such `System.Type` might not have a workable constructed `MethodTable`, but should still compare equal to the `typeof`.

An example of when this could happen is when the type is used in a custom attribute metadata blob - such type may even have no `MethodTable` at all.

The fix is to look not just at `MethodTable` but also at the metadata for the type.

…d come from deps or app-local directory (#107484)

Stop explicitly adding app passed on command line to TPA. This was an old workaround that should no longer be needed (the .deps.json - including for csc - has the app assembly). Having this explicitly added would fail with a confusing message about the deps.json and mismatched file extensions if a user did `dotnet app.exe`. This change makes it so that we end up showing the same error as if the user tried to do an Assembly.Load on an app.exe that is not a managed assembly. This also makes the failure message match the case where there was no .deps.json.
