Johnny Chen a9f39bdbb6 Add Rt2 to the asm format string for 32-bit Thumb load/store register dual 
instructions.  Thumb does not have the restriction that t2 = t+1.

Douglas Gregor 1a68ab6c83 Make use of available_externally linkage for vtables when the 
non-inline key function of a class template instantiation, when no key
function is present, the class template instantiation itself was
instantiated with an explicit instantiation declaration (aka extern
template). I'm fairly certain that the C++0x specification gives us
this lattitude, although GCC doesn't take advantage of it.

Jakob Stoklund Olesen aee326860c Don't specify CR sub-registers as implicit defs of BL instructions. 
It is enough to give the super registers CR0, CR1, ..., and specifying the
sub-registers as well causes confusion in the liveness computations.

Jakob Stoklund Olesen 4cb7702c4f Remove livein checks from machine code verifier. 
A phi operand that is implicitly defined in a predecessor becomes an undefined
register after phi elimination. This causes a lot of false positives when the
verifier is checking if live-in registers are live-out from all predecessors.

Removing the verifier checks seems like a better solution than insisting on
IMPLICIT_DEF instructions in predecessor blocks.

Douglas Gregor a318efd1f2 Improve key-function computation for templates. In particular: 
- All classes can have a key function; templates don't change that.
  non-template classes when computing the key function.
  - We always mark all of the virtual member functions of class
  template instantiations. 
  - The vtable for an instantiation of a class template has weak
  linkage. 

We could probably use available_externally linkage for vtables of
classes instantiated by explicit instantiation declarations (extern
templates), but GCC doesn't do this and I'm not 100% that the ABI
permits it.

Dan Gohman 1117a59b84 Some versions of GCC don't like non-static data members in sizeof 
in this context.

Dan Gohman 5976e7d5dd Add a SmallBitVector class, which mimics BitVector but uses only 
a single pointer (PointerIntPair) member. In "small" mode, the
pointer field is reinterpreted as a set of bits. In "large" mode,
the pointer points to a heap-allocated object.

Also, give BitVector empty and swap functions.

And, add some simple unittests for BitVector and SmallBitVector.
