For x86 targets, do not do sibling call optimization when materializing the callee's address would require a GOT relocation. We can still do tail calls to internal functions, hidden functions, and protected functions, because they do not require this kind of relocation. It is still possible to get GOT relocations when the user explicitly asks for it with musttail or -tailcallopt, both of which are supposed to guarantee TCO. Based on a patch by Chih-hung Hsieh.
