This simplifies the usage and implementation of ELFObjectFile by using ELFType to replace: <endianness target_endianness, std::size_t max_alignment, bool is64Bits> This does complicate the base ELF types as they must now use template template parameters to partially specialize for the 32 and 64bit cases. However these are only defined once. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172515 91177308-0d34-0410-b5e6-96231b3b80d8
