[JitDiff X64] [EgorBo] JIT: Fold redundant CHKCAST through VN-to-handle asse ...

[00:00:01] [Setup runtime]     still went through CORINFO_HELP_CHKCASTANY.
[00:00:01] [Setup runtime]     
[00:00:01] [Setup runtime]     Producer: optAssertionGenJtrue records a new `O1K_VN ==/!= O2K_CONST_INT`
[00:00:01] [Setup runtime]     assertion when one side of an EQ/NE is a class-handle constant
[00:00:01] [Setup runtime]     (via the new AssertionDsc::CreateConstVNAssertion factory).
[00:00:01] [Setup runtime]     
[00:00:01] [Setup runtime]     Consumer: optAssertionProp_Call (CHKCAST helpers) now also tries to
[00:00:01] [Setup runtime]     resolve a non-constant castToArg through these assertions. If we
[00:00:01] [Setup runtime]     recover a handle and gtGetClassHandle(objArg) is a Must-cast match,
[00:00:01] [Setup runtime]     the helper call is dropped.
