From 439661395fd2a2a832dba01c65bc88718528313c Mon Sep 17 00:00:00 2001

Subject: 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.
