Printer.cpp: Ditch addRequired/getAnalysis, because they leave

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().
