f158da2f78 Implement code to keep the stack pointer aligned to an 8 byte boundary. 
This improves the performance of the power benchmark by a few percent.
This will be neccesary for SSE code, which requires 16 byte alignment of
the stack.

 the scale * index part at compile time instead of using the fancy
 load instruction. Just because an instruction set has wacky addressing
 modes doesn't mean we ought to use them (at least, if you believe Dave
 Patterson).

lib/Target/X86/X86InstrBuilder.h: Add some comments.

test/Regression/Jello/test-loadstore.ll:  Let main return int 0.

20244b7e2c This checkin is brought to you by the brian gaeke allnighter fund. 
(lib/Target/X86) InstSelectSimple.cpp:
 Include llvm/DerivedTypes.h and iostream.
 Refactor visitMul out into a wrapper around doMultiply(), so that we
  can do multiplications on temporary values when we are doing
  getelementptrs.
 Refactor part of getReg out into makeAnotherReg, so that we can create
  registers willy-nilly to hold temporary values, when we are doing
  getelementptrs.
 Add stub implementations of visitMallocInst and visitAllocaInst.
 Add initial implementation of visitGetElementPtrInst.
 In copyConstantToRegister:
  We throw a *lot* of our asserts here. So, when we want to throw an
   assert, print out to stderr whatever expr or whatever constant made
   us barf.
  Support copying ConstantPointerNull to register, using a move immediate
   of zero.
 Rename FLDr4 and FLDr8 to FLDr32 and FLDr64, so that they match the meanings
  of the numbers in the other instruction names. All uses modified.
 Teach visitCallInst to extract byte- and short-class return values
  from subregs of EAX.  Add a FIXME note about how we would do it for
  float-class return values.
 Add a FIXME note about how we would cast float to int and back.

X86InstrInfo.def:
 Rename FLDr4 and FLDr8 to FLDr32 and FLDr64, so that they match the meanings
  of the numbers in the other instruction names. All uses modified.

(tools/jello) GlobalVars.cpp:
 Include iostream.
 If we have to emit a floating-point constant to memory, gamble and use
  the same method as for ints.
 If we have to emit a ConstantPointerNull to memory, try using a "void *"
  and "NULL".
 Otherwise, if we are going to throw an assert, print out whatever constant
  made us barf, first.

86764d778e Target/X86/Printer.cpp: Add sizePtr function, and use it instead of 
" <SIZE> PTR " string when emitting assembly.

Target/X86/X86InstrInfo.def: Tidy up a bit:
 Squashed everything down to 118 chars wide, wrapping lines so that
 comment is at the same point on each line. Rename "NoImpRegs" as
 "NoIR". (most instructions have NoImpRegs twice on a line, so this
 saves 10 columns).

 Also, annotate various instructions with flags for size of memory operand.
  (MemArg16, MemArg32, MemArg64, etc.)

Target/X86/X86InstrInfo.h: Define flags for size of memory operand.
 (MemArg16, MemArg32, MemArg64, etc.)
