1ec15e0428 ConstantTypeMustBeLoaded has been incorporated into SparcV9PreSelection, its 
only user.

a71776e676 As it happens, none of these TargetInstrInfo methods which are only 
used in the SparcV9 backend really have anything to do with
TargetInstrInfo, so we're converting them into regular old global
functions and moving their declarations to SparcV9InstrSelectionSupport.h.
(They're mostly used as helper functions for SparcV9InstrSelection.)

3ecdcd18c5 Add parent pointer to MachineInstr that points to owning 
MachineBasicBlock. Also change opcode to a short and numImplicitRefs
to an unsigned char so that overall MachineInstr's size stays the
same.

6f2c46cd52 Nice tasty llc fixes. These should fix LLC for x86 for everything in 
SingleSource except oopack and Oscar.  (Sorry, Oscar.)

include/llvm/Target/TargetInstrInfo.h: Remove virtual print method. Add
 accessors for ImplicitUses/Defs.
lib/Target/TargetInstrInfo.cpp: Remove virtual print method. If you
 really wanted this, just use MI->print(O, TM); instead...
lib/Target/X86:
FloatingPoint.cpp: ...like this.
X86InstrInfo.h: Remove virtual print method. Define the PrintImplUses
 target-specific flag bit.
X86InstrInfo.def: Add the PrintImplUses flag to all the instructions
 which implicitly use CL, because the assembler needs to see the CL in
 order to generate the right instruction.
Printer.cpp: Ditch fnIndex at Chris's request. Now we use CurrentFnName
  to name constants in the constant pool for each function instead. This
  avoids keeping state between runOnMachineFunction() invocations, which
  is a no-no. Having MangledGlobals be global is a bogon I'd like to get
  rid of too, but making it a static member of Printer causes link errors
  (why???).
 Make NumberForBB into a member of Printer instead of a global, too.
 Make printOp and printMemReference into methods of Printer.
 X86InstrInfo::print is now Printer::printMachineInstruction, because
  TargetInstrInfo::print is history. (Because of this, we have to qualify
  the names of some TargetInstrInfo methods we call.)
 Print out the ImplicitUses field of any instruction we print that has
  the PrintImplUses bit set.

151f7484ab NOP instructions are pseudo-instructions. We should not have them explicitly in 
our representation, since they are usually special cases of already-existing
instructions.

This abstracts away methods that let a pass create and verify a NOP instruction,
without relying on a `NOP' enum to be in existence in the target's instruction
info descriptor.
