Bob Wilson db46af0461 Implement Neon VTRN instructions. For now, anyway, these are selected 
directly from the intrinsics produced by the frontend.  If it is more
convenient to have a custom DAG node for using these to implement shuffles,
we can add that later.

Daniel Dunbar 713302883e llvm-mc/AsmMatcher: Switch to a unified function to convert operands to MCInst, 
so that terminal states are as simple as possible.
 - If we were willing to assume that the order that operands get inserted in the
   MCInst is fixed we could actually dispose with this altogether, although it
   might be nice to have the flexibility to change it later.

Douglas Gregor 2c742024ff Introduce reference counting for statements and expressions, using it 
to allow sharing of nodes. Simplifies some aspects of template
instantiation, and fixes both PR3444 and <rdar://problem/6757457>.

Bob Wilson 40ff4a190f Add new intrinsics for Neon VTRN, VZIP and VUZP operations. Modeling these 
as vector shuffles did not work out well.  Shuffles that produce double-wide
vectors accurately represent the operation but make it hard to do anything
with the results.  I considered splitting them up into 2 shuffles, one to
write each register separately, but there doesn't seem to be a good way to
reunite them for codegen.

Daniel Dunbar 11595b20fc Add DEBUG_WITH_TYPE as a clean alternative to tweaking DEBUG_TYPE. 
This:
--
#undef DEBUG_TYPE
#define DEBUG_TYPE "foo"
DEBUG(...)
#undef DEBUG_TYPE
#define DEBUG_TYPE ""
--
becomes this:
--
DEBUG_WITH_TYPE("foo", ...)

Chris Lattner 2d423d5a95 fix the column output stuff in the asmwriter from being dynamic and 
driven by TAI to being static, driven by tblgen.  This means that a
target doesn't get impacted by this stuff at all if it doesn't opt
into it.

Argyrios Kyrtzidis 885e6382eb Modifications to dyn_cast/cast to make them work for objects too, instead of only pointers. 
The use case is if you have a wrapper class:

class Base {
  void *Ptr;
public:
  Base() : Ptr(0) { }
  operator bool() const { return Ptr; }
.....
}

and sub-wrappers that have exactly the same size:

class Sub : public Base {
public:
....
static bool classof(const Base*);
}

and in the code you would do:

void f(Base b) {
  Sub sub = dyn_cast<Sub>(b);
  if (sub) {
    ....
  }
}

Kevin Enderby d9f952948e Added Mac OS X assembler style conditional assembly. I may come back and see if 
I can clean this up a bit more and do way with the TheCondState and just use
the top element on the TheCondStack if not empty.  Also may tweak the code
around ParseConditionalAssemblyDirectives() to simplify the AsmParser code.
