    [interpreter] Switch context during stack unwinding. · 76bfc16b
    mstarzinger authored
    This implements proper context switching while unwinding the stack due
    to an exception being handled in interpreted code. The context under
    which the handler is scoped is being preserved in a dedicated register
    while the try-block is running. Both, the stack unwinding machinery as
    well as the graph builder, restore the context from that register.
