[ELF2] Check for TLS mismatch in symbol resolution. The linker should generate an error if a TLS symbol is resolved for a non-TLS reference and vice versa. The patch addresses PR24244 (https://llvm.org/bugs/show_bug.cgi?id=24244) Differential Revision: http://reviews.llvm.org/D13550 llvm-svn: 249817

Change the error message format for duplicate symbols. This patch is intended to improve readability of "duplicate symbol" error messages. Without this patch: /ssd/clang/bin/ld.lld: error: /ssd/llvm-project/lld/ELF/Relocations.cpp:1054: duplicate symbol 'lld::elf::demangle(llvm::StringRef)' /ssd/clang/bin/ld.lld: error: /ssd/llvm-project/lld/ELF/Strings.cpp:93: previous definition was here With this patch: /ssd/clang/bin/ld.lld: error: duplicate symbol: lld::elf::demangle(llvm::StringRef) >>> defined at Strings.cpp:93 (/ssd/llvm-project/lld/ELF/Strings.cpp:93) >>> Strings.cpp.o:(lld::elf::demangle(llvm::StringRef)) in archive lib/liblldELF.a >>> defined at Relocations.cpp:1054 (/ssd/llvm-project/lld/ELF/Relocations.cpp:1054) >>> Relocations.cpp.o:(.text+0x4C30) in archive lib/liblldELF.a Discussion thread: http://lists.llvm.org/pipermail/llvm-dev/2017-March/111459.html Differential Revision: https://reviews.llvm.org/D31507 llvm-svn: 299280
