7279122e66 Remove default operands that are never used

413746e983 * Make MachineOperand ctors private, so MachineOperand can only be created
by MachineInstr.
* Add a bunch of new methods to allow incremental addition of operands to the
  machine instr instance.

572f5c8c0c 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

27a08935ca - 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!

7a4be9580e 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.

6d35326cd5 1. Add a bottom-up pass on BURG trees that is used to fix constant operands.
Needs to be bottom up because constant values may be forward-substituted
   to their uses (i.e., into the parent in the BURG tree).
2. Move most of the constant-fixup code into machine-indepedent file
   InstrSelectionSupport.cpp.
