Made lldb_private::ArchSpec contain much more than just an architecture. It

now, in addition to cpu type/subtype and architecture flavor, contains:
- byte order (big endian, little endian)
- address size in bytes
- llvm::Triple for true target triple support and for more powerful plug-in
  selection.
