Bill Wendling 578865ff3d Only check the ordering if there is an ordering for each nodes.

Bill Wendling 0a7056fe52 Add a semi-primitive form of scheduling via the "SDNode ordering" to the 
bottom-up scheduler. We prefer the lower order number.

John McCall 1be1c63634 Add Expr::EvaluateAsBooleanCondition(), which does unprincipled folding to 
try to evaluate an expression as a constant boolean condition.  This has
the same intended semantics as used in folding conditional operators.

Ted Kremenek a44d99c934 Add C API hook 'clang_getDeclExtent()', which returns the source extent of a declaration. This implements <rdar://problem/7280072>.

Dan Gohman f34b289057 Move this test from test/Transforms/IndVarSimplify to 
test/CodeGen/X86, as doesn't use -indvars, and it does use
llc -march=x86-64.

Bill Wendling 03f0af372c Don't assign the shift the same type as the variable being shifted. This could 
result in illegal types for the SHL operator.

Johnny Chen 567945636f Undo r92785, it caused test failure.

Dan Gohman 404a984780 Don't use the ISD::NodeType enum for SDNode opcodes, as CodeGen 
uses several kinds of opcode values which are not declared within
that enum. This fixes PR5946.

Chris Lattner f88dd5ed64 remove two trunc xforms that are subsumed by EvaluateInDifferentType. 
The only difference is that EvaluateInDifferentType checks to ensure
they are profitable before doing them :)

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.
