0a0266865a Remove support for the MultiObject flag, which was fundamentally broken

9a0da3e531 Instcombine cast (getelementptr Ptr, 0, 0, 0) to ... into: cast Ptr to ... 
This fixes type safety problems in a variety of benchmarks that were confusing
DSA.

2840a1b4ee For 16 and 32-bit multiplies, use the IMUL instruction instead of the MUL instruction. 
This allows us to not force the use of the EAX/AX registers!

365e583866 * Changes to make NodeType be private to DSNode. 
* Add new MultiObject flag to DSNode which keeps track of whether or not
  multiple objects have been merged into the node, allowing must-alias info
  to be tracked.

a734842f8a 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.

beb320af87 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.

19420e8daf 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.

into a new function FPCSafeToPrint(), and use it in printConstant()

floating-point constants or as references to stack-allocated variables.

04d082abe5 Add #ifdef hack for MAP_ANONYMOUS being spelled MAP_ANON on some platforms. 
(We're already talking about autoconf'ing this, so I'm assuming this hack
will be short-lived...I just don't want it to get lost in my working files.)

0c7e4fdfa2 Do not link in the Sparc JIT when building on X86. Eventually the sparc will not 
link in the X86 JIT either, but this makes testing easier.

For some reason, the sparc JIT was breaking the X86 JIT when it was linked in. :(

44689264b2 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.
