Introduce MCCodeGenInfo, which keeps information that can affect codegen
(including compilation, assembly). Move relocation model Reloc::Model from TargetMachine to MCCodeGenInfo so it's accessible even without TargetMachine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135468 91177308-0d34-0410-b5e6-96231b3b80d8
