fix crash in findFrameMapInSimpleTable due to bug in instanceof implementation

Browse Source 
We weren't adding entries to the frame map for calls to the instanceof
thunk when compiling methods.  However, that thunk may trigger a GC,
in which case we'll need to unwind the stack, which will lead to a
crash if we don't have a frame map entry for that instruction.
