0e2cf7606d Several fixes:
(1) Applied patch from Casey to implement iterator::operator= correctly:
    it should use a pointer, not a reference.
(2) Added operators == and !=, and method all().
(3) Important bug fix: excess bits need to be ignored in operations
    like ==, count(), and all().  We do this by ensuring excess bits
    in the last bitset are always 0.

61ff02982f Fix logical error in TD pass: we should clear Mod/Ref bits of each caller
before inlining their graphs into a function.  To support this,
added flags to CloneFlags to strip/keep Mod/Ref bits.

9a96428297 (1) Bug fix that was causing nodes with dangling references to be freed.
We run removeDeadNodes() on the TD graph up front before using it.
(2) Major enhancement to printing of results: now we list the actual objects
    that are mod/ref instead of just printing the bit vectors.
Also an important bug fix in TDDataStructures pass (no change here):
clear Mod/Ref bits of callers before inlining into a function.

35880f394f 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.
