X86: enable TLS on Windows itanium Windows itanium is nearly identical to windows-msvc (MS ABI for C, itanium for C++). Enable the TLS support for the target similar to the MSVC model. llvm-svn: 271797

[llvm-readobj] Change -long-option to --long-option in tests. NFC We use both -long-option and --long-option in tests. Switch to --long-option for consistency. In the "llvm-readelf" mode, -long-option is discouraged as it conflicts with grouped short options and it is not accepted by GNU readelf. While updating the tests, change llvm-readobj -s to llvm-readobj -S to reduce confusion ("s" is --section-headers in llvm-readobj but --symbols in llvm-readelf). llvm-svn: 359649
