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.

3dc8d444ff When internalizing global ctor/dtor list, also mark it constant. This is gross, but 
until DSA is working all of the time and is totally reliable, we do this.

0a940fa30a - Fixed name mangling conditions to handle 'linkonce' linkage type. In 
particular, name mangling for GlobalValues only occurs when the linkage type is
internal or when the name must be mangled to avoid a collision.  See comments in
CWriter::getValueName for more information.

- 'inline' keyword is now emitted for functions with 'linkonce' linkage type.

- Fixed typos.

6c5d67b96f It seems likely that floats would need a cast too, because they are 
ordinarily promoted to doubles.

aac87d1e58 Do not mark ALL terminators live if any instruciton in the block is live. We only 
want to mark it live if it is an unconditional branch.  This fixes bug:

62947dbf9e Fix 2003-06-23-PromotedExprs.llx -- if we are adding two bytes we better 
explicitly cast the result to be a byte, or C will gleefully promote it
to int.
