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!

eed53d4b81 Remove a 'using' directives from a header file. Using directives cause 
global changes, so aren't good for headers.

bacbe6b240 Interface to class MachineCodeForBasicBlock. 
Moved here from MachineInstr.h to make it an annotation on BasicBlock.

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.
