            `cti_vm_throw'"
            https://bugs.webkit.org/show_bug.cgi?id=28422
    
            * jit/JITStubs.cpp:
            Mark cti_vm_throw symbol as PLT-indirect symbol, so it doesn't end up
            in text segment causing relocation errors on amd64 architecture.
            Introduced new define SYMBOL_STRING_RELOCATION for such symbols.
