09e460662a Completely eliminate def&use operands. Now a register operand is EITHER a
def operand or a use operand.

ceb408f6a2 Change "value" in MachineOperand to be a GlobalValue, as that is the only
thing that can be in it.  Remove a dead method.

9696a90ee6 * store immediate values as int64_t, not int. come on, we should be happy
when there are immediates, let's not worry about the memory overhead of
this :)

* add addU64Imm(uint64_t val) to machineinstrbuilder

(seriously: this seems required to support 64-bit immediates cleanly. if it
_really_ gets on your nerves, feel free to pull it out ;) )

coming up next week: "all your floating point constants are belong to us"

7b55d4fce2 Instead of storing std::string's for ExternalSymbol references, rely on the
fact that all ExternalSymbols are actually string literals with static storage.
Thus we don't have to do anything special to hold them and we certainly don't
have to copy string data around.

ca4f6ebefc Allow machine operands to represent global variables with offsets. This is
useful when you have a reference like:

int A[100];

void foo() { A[10] = 1; }

In this case, &A[10] is a single constant and should be treated as such.

Only MO_GlobalAddress and MO_ExternalSymbol are allowed to use this field, no
other operand type is.

This is another fine patch contributed by Jeff Cohen!!

6a8a9b4413 Continue Alkis's int64_t cleanup. This makes all of the immediate related
methods take an int or unsigned value instead of int64_t.

Also, add an 'addImm' method to the MachineInstrBuilder class, because the
fact that the hardware sign or zero extends it does not/should not matter
to the code generator.  Once the old sparc backend is removed the difference
can be eliminated.

890f92328d Move MOTy::UseType enum into MachineOperand. This eliminates the
switch statements in the constructors and simplifies the
implementation of the getUseType() member function. You will have to
specify defs using MachineOperand::Def instead of MOTy::Def though
(similarly for Use and UseAndDef).

reading code much easier than just seeing "true, false" especially when
default parameters default one but not both arguments.

convenience method.  Fix typo in comment.

 Use MOVZX/MOVSX instead of MOV instructions with sign extend instructions.
 Take out LEAVE instructions.
 32-bit IDIV and DIV use CDQ, not CWQ (CWQ is a typo).
 Fix typo in comment and remove some FIXME comments.
lib/Target/X86/Printer.cpp: Include X86InstrInfo.h and llvm/Function.h.
 Add some simple code to Printer::runOnFunction to iterate over
  MachineBasicBlocks and call X86InstrInfo::print().

 implicit defs "Void".  Add more sign/zero extending "move" insns
 (movsx, movzx).
