This adds support for an -mattr option to the gold plugin and to llvm-lto. This allows the caller to specify details of the subtarget architecture, like +aes, or +ssse3 on x86. Note that this requires a change to the include/llvm-c/lto.h interface: it adds a function lto_codegen_set_attr and it increments the version of the interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207279 91177308-0d34-0410-b5e6-96231b3b80d8
