Refactor TargetMachine, pushing handling of TargetData into the target-specific subclasses. This has one caller-visible change: getTargetData() now returns a pointer instead of a reference.
This fixes PR 759. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28074 91177308-0d34-0410-b5e6-96231b3b80d8
