3c3ce98530 - MachineInstr now keeps a ptr to TargetInstrDescriptor instead of Opcode.

539df43e4b setOperand should not zap the operand list or add implicit operands to an 
instruction.  Doing so breaks the FP stackifier, the alpha branch selector
the sparc fpmover.

This fixes PR1012 and CodeGen/X86/fp-stack-compare.ll

77af6ac5e8 - Let MachineInstr ctors add implicit def and use operands. Other operands 
will be inserted before these operands. If the opcode changes (by
  setOpcode), the implicit operands are updated as well.
- Added IsKill, IsDead fields to MachineOperand in preparation for changes
  that move kill / dead info to MachineInstr's.

55772ccfd6 Instructions with variable operands (variable_ops) can have a number required 
operands. e.g.
def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops),
                "call {*}$dst", [(X86call GR32:$dst)]>;
TableGen should emit operand informations for the "required" operands.

Added a target instruction info flag M_VARIABLE_OPS to indicate the target
instruction may have more operands in addition to the minimum required
operands.

4ca2ea5b43 JumpTable support! What this represents is working asm and jit support for 
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.

3065220deb 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!!
