This reverts r362990 (git commit 374571301dc8e9bc9fdd1d70f86015de198673bd) This was causing linker warnings on Darwin: ld: warning: direct access in function 'llvm::initializeEvexToVexInstPassPass(llvm::PassRegistry&)' from file '../../lib/libLLVMX86CodeGen.a(X86EvexToVex.cpp.o)' to global weak symbol 'void std::__1::__call_once_proxy<std::__1::tuple<void* (&)(llvm::PassRegistry&), std::__1::reference_wrapper<llvm::PassRegistry>&&> >(void*)' from file '../../lib/libLLVMCore.a(Verifier.cpp.o)' means the weak symbol cannot be overridden at runtime. This was likely caused by different translation units being compiled with different visibility settings. llvm-svn: 363028
