d7908f679e 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.

54f6032dae - 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.

explicitly cast the result to be a byte, or C will gleefully promote it
to int.

96b07e54dd Rename many instructions to their Intel asm-compatible names. This
involves removing the [bwl] suffixes from instruction names, as well
as some other distinguishing marks (32/64/80 on fp insns, _i suffixes, etc.)

Lowercase all instr. names as well for consistency's sake.

9e474c4ec8 Add Initialization and Finalization methods for the Printer pass,
to print various things on a module-by-module basis (currently, only the
former is used).

Don't print < > around names. The assembler can't take it.

Print pseudoinstructions only as comments. The poor little assembler can't
take that, either.

2e2f2dcd6a lib/Target/Sparc/Sparc.cpp:
Move LowerAllocations, PrintFunction, and SymbolStripping passes, and
  the corresponding -disable-strip and -d options, over here to the SPARC
  target-specific bits of llc. Rename -d to -dump-asm.

tools/llc/Makefile:
 Reindent. Add x86 library so that llc compiles again.

tools/llc/llc.cpp:
 Remove support for running arbitrary optimization passes. Use opt instead.
 Remove LowerAllocations, PrintFunction, and SymbolStripping passes, as noted
  above.
 Allow user to select a backend (x86 or SPARC); default to guessing from
  the endianness/pointer size of the input bytecode file.
 Fix typos.
 Delete empty .s file and exit with error status if target does not support
  static compilation.

a8ab89e3da Fairly major change: emit fixed sized allocas in the entry block as a variable,
instead of a variable pointer and an alloca.  All accesses to the variable then
use the address-of operator to access it.  This plays better with the internal
GCC code generation phases, which bail early on functions which contain allocas.
It also makes the code a bit easier to read.
