Subject: LLVMTargetMachine: Add functions to create MIModuleInfo/MIFunction;
 NFC

Add convenience function to create MachineModuleInfo and
MachineFunctionAnalysis passes and add them to a pass manager.

Despite factoring out some shared code in
LiveIntervalTest/LLVMTargetMachine this will be used by my upcoming llc
change.
