the sparc fpmover.

  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.

                "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.

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.

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!!

Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

* Fix spacing, grammar in comment
* Make code layout consistent
* Wrap code at 80 cols
* Delete spurious blank lines

Made a fix so that you can print out MachineInstrs that belong to a MachineBasicBlock that is not yet attached to a MachineFunction. This change includes changing the third operand (TargetMachine) to a pointer for the MachineInstr::print function.
