7aaea42f1e Minor cleanups: 
* Document the MOTy namespace correctly for doxygen
  * Eliminate usage of the MachineOpCode typedef, which should eventually
    be eliminated entirely.

ab50c0aee5 Renamed MachienOperand::opIsDef to MachineOperand::opIsDefOnly() 
and related functions and flags.  Fixed several bugs where only
"isDef" was being checked, not "isDefAndUse".

940cfa8597 Instead of checking op.getType() against MO_VirtualRegister and 
MO_MachineRegister, we no longer distinguish Virtual vs. Machine registers
externally, they're ALL registers, all equal.

Registers are only differentiated whether they are >=
MRegisterInfo::FirstVirtual or not.

16b1ec97f0 Convert to use an enum to access def/use/use&def information. These make 
reading code much easier than just seeing "true, false" especially when
default parameters default one but not both arguments.

4acb69b4ea Remove separate vector of implicit refs from MachineInstr, and 
instead record them as extra operands in the operands[] vector.
Also, move CallArgsDescriptor into this class instead of making it an
annotation on the machine instruction.

7000bbb63f Fairly major overhaul of MachineInstr & Operand classes 
- Inline methods that are mostly a single line anyway
  - Eliminate several methods that were never called
  - Group methods a bit more consistently

dfc8fbf16b - Two minor improvements to the MachineInstr class to reduce footprint and 
overhead: Merge 3 parallel vectors into 1, change regsUsed hash_set to be a
    bitvector.  Sped up LLC a little less than 10% in a debug build!

a110ccca19 Moved class MachineCodeForBasicBlock to MachineCodeForBasicBlock.{cpp,h}. 
An (explicit or implicit) operand may now be both a def and a use.
Also add a set of regs used by each instruction.
dump() no longer takes an optional argument, which doesn't work in gdb.
