llvm-6502/lib/Target/Alpha/AlphaTargetMachine.h
Evan Cheng 34ad6db8b9 - Move CodeModel from a TargetMachine global option to MCCodeGenInfo.
- Introduce JITDefault code model. This tells targets to set different default
  code model for JIT. This eliminates the ugly hack in TargetMachine where
  code model is changed after construction.
