/* Inline context encoding (different from what native does):
* bits 31:30: 3 ignore (includes INLINE_FRAME_CONTEXT_IGNORE=0xFFFFFFFF)
* 2 regular frame
* 1 frame with inlined function(s).
* 0 init (includes INLINE_FRAME_CONTEXT_INIT=0)
* so either stackwalkex is called with:
* - inlinectx=IGNORE, and we use (old) StackWalk64 behavior:
* - inlinectx=INIT, and StackWalkEx will upon return swing back&forth between:
* INLINE when the frame is from an inline site (inside a function)
* REGULAR when the frame is for a function without inline site
* bits 29:00 depth of inline site (way too big!!)
* 0 being the lowest inline site
