[PATCH] perf uprobe: Skip prologue if program compiled without optimization

Function prologue prepares stack and registers before executing function logic. When target program is compiled without optimization, function parameter information is only valid after prologue. When we probe entrypc of the function, and try to record function parameter, it contains garbage value.
