Partial expand of casts to non-sealed classes

[EgorBo]

Currently, we don't expand casts/isinst to non-sealed classes, e.g.

public class MyClass
{
    static bool Test(object o) => o is MyClass;


    static void Test2(object o)
    {
        if (o is MyClass p)
        {
            p.DoWork();
        }
    }


    [MethodImpl(MethodImplOptions.NoInlining)]
    public void DoWork() {}
}

Here is the codegen for Test and Test2:

; Method Program:Test(System.Object):bool
G_M4425_IG01:
       sub      rsp, 40
G_M4425_IG02:
       mov      rdx, rcx
       mov      rcx, 0xD1FFAB1E
       call     CORINFO_HELP_ISINSTANCEOFCLASS
       test     rax, rax
       setne    al
       movzx    rax, al
G_M4425_IG03:
       add      rsp, 40
       ret      
; Total bytes of code: 36


; Method Program:Test2(System.Object)
G_M61455_IG01:
       sub      rsp, 40
G_M61455_IG02:
       mov      rdx, rcx
       mov      rcx, 0xD1FFAB1E
       call     CORINFO_HELP_ISINSTANCEOFCLASS
       test     rax, rax
       je       SHORT G_M61455_IG05
G_M61455_IG03:
       mov      rcx, rax
G_M61455_IG04:
       add      rsp, 40
       jmp      Program:DoWork():this
G_M61455_IG05:
       add      rsp, 40
       ret      
; Total bytes of code: 44

As you can see, we just call CORINFO_HELP_ISINSTANCEOFCLASS.
I propose we also expand cases like this but with that call as a fallback.
Basically, optimize if (CORINFO_HELP_ISINSTANCEOFCLASS(obj, MyNonSealedType) to if ((obj != null && obj->pMT == MyNonSealedType) || CORINFO_HELP_ISINSTANCEOFCLASS(obj, MyNonSealedType))

Here is the new codegen:

G_M4425_IG03:
       mov      rdx, 0xD1FFAB1E
       cmp      qword ptr [rax], rdx  ;; o is exactly BaseClass ?

G_M4425_IG05:
       test     rax, rax ;; redundant, but it's a different issue.
       setne    al
       movzx    rax, al

Benchmarks

I wrote a simple benchmark to check benefits or overhead (in case of subclasses): https://gist.github.com/EgorBo/a3ac2b1f5c6e182acdd5f5d43c8335ec

Here are the results:

A 10% (+0.2ns) overhead for a case when Subclass is passed (and we expected BaseClass), but a significant win for cases where null or BaseClass are passed.

PS: we'll avoid the overhead at all with PGO, see #55325
PS2: the new codegen is not super-efficient and will be improved, see #55841 (comment))

[EgorBo]

The diff is quite big so I guess I can enable this opt only for really hot methods (with PGO data).
