Re-apply this patch, hopefully I will get away without any warnings in the constructor now. This patch removes the MachineFunctionAnalysis. Instead we keep a map from IR Function to MachineFunction in the MachineModuleInfo. This allows the insertion of ModulePasses into the codegen pipeline without breaking it because the MachineFunctionAnalysis gets dropped before a module pass. Peak memory should stay unchanged without a ModulePass in the codegen pipeline: Previously the MachineFunction was freed at the end of a codegen function pipeline because the MachineFunctionAnalysis was dropped; With this patch the MachineFunction is freed after the AsmPrinter has finished.
