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.

de6ac9b0ff * 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.

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!

62f569e4ea Add support for marking each operand as a %hh, %hm, %lm or %lo. 
Represent previous bools and these ones with flags in a single byte
per operand.

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.

edc1adae11 Bug fix in setting CC register. 
Also use distinct names for the three types of SetMachineOperand
to avoid painful overloading problems and errors.

34b17e8a37 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.
