[Interpreter]: Fix IC::GetSharedFunctionInfo for the interpreter.

Browse Source 
IC::GetSharedFunctionInfo get's the JS frame which called the IC. When the
function is running in the interpreter, there is a Bytecode handler stub
frame between the IC and the JS frame. Modify IC::GetSharedFunctionInfo to
handle this.
