[LTO] Keep linkonce_odr symbols when appropriate. Ensure we keep the symbol we need to before it reaches the Writer (and hit an assertion), changing its linkage from linkonce_odr to weak. For a more detailed description of the problem, see PR19901 where a similar problem was fixed for the gold plugin. Thanks to Rafael for providing a testcase. llvm-svn: 264111

[ELF] - Error out when R_X86_64_PC32/R_X86_64_32 are used against preemptible symbol when linking shared object. When R_X86_64_PC32/R_X86_64_32 relocations are used against preemptible symbol and output is position independent, error should be generated.
