want to mark it live if it is an unconditional branch.  This fixes bug:
ADCE/2002-05-28-Crash.ll and makes this pass _much_ more useful.

  Replace (cast (sub A, B) to bool) -> (setne A, B)
  Replace (cast (add A, B) to bool) -> (setne A, -B)

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

Remove isnan; it's too unportable to handle cleanly at this point.

This fixes type safety problems in a variety of benchmarks that were confusing
DSA.

This allows us to not force the use of the EAX/AX registers!

  multiple objects have been merged into the node, allowing must-alias info

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.

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.

 (non-working) of llc guts for X86, and add a prototype for it.

llvm-svn: 6779

 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.

into a new function FPCSafeToPrint(), and use it in printConstant()
and printFunction() to decide whether we should output ConstantFPs as
floating-point constants or as references to stack-allocated variables.

lib/VMCore/AsmWriter.cpp: Fix an apparent typo in the code mentioned above.
