In D34993, we discussed and concluded that we should drop `__real_ symbol from the symbol table, but I did the opposite in D50569. This patch is to drop `__real_` symbol. MaskRay's note: omitting `__real_` is important if it is undefined: otherwise a subsequent link may error due to the undefined `__real_` in .dynsym Differential Revision: https://reviews.llvm.org/D51283
