Printer::doFinalization() out in the cold. Now we pass in a TargetMachine to Printer's constructor and get the TargetData from the TargetMachine. Don't pass TargetMachine or MRegisterInfo objects around in the Printer. Constify TargetData references. X86.h: Update comment and prototype of createX86CodePrinterPass(). X86TargetMachine.cpp: Update callers of createX86CodePrinterPass(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7275 91177308-0d34-0410-b5e6-96231b3b80d8
