Subject: - 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.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135580 91177308-0d34-0410-b5e6-96231b3b80d8
