The following commit introduced stack overflow exception handling on Windows x64:


The problem is that this commit is not full AOT compliant, so currenlty it is not possible to run any full AOT compiled code. Needs to be fixed using a trampoline in AOT image (similar to other exception handling methods). The emitted code also needs to work in the full AOT use case, so smaller adjustments are needed there as well. Quick fix is to disable the code on x64 when running full AOT.
