 - Add support for -MP (phony targets).
 
 - Use raw_ostream for output instead of std::string concatenation.
 
 - Break long lines in a GCC (4.2) compatible manner.

 - Output dependents in #included order (to match GCC).

  - CastExpr is the root of all casts
  - ImplicitCastExpr is (still) used for all explicit casts
  - ExplicitCastExpr is now the root of all *explicit* casts
  - ExplicitCCastExpr (new name needed!?) is a C-style cast in C or C++
  - CXXFunctionalCastExpr inherits from ExplicitCastExpr
  - CXXNamedCastExpr inherits from ExplicitCastExpr and is the root of all
    of the C++ named cast expression types (static_cast, dynamic_cast, etc.)
  - Added classes CXXStaticCastExpr, CXXDynamicCastExpr, 
    CXXReinterpretCastExpr, and CXXConstCastExpr to 

Also, fixed returned-stack-addr.cpp, which broke once when we fixed
reinterpret_cast to diagnose double->int* conversions and again when
we eliminated implicit conversions to reference types. The fix is in
both testcase and SemaChecking.cpp.

Most of this patch is simply support for the renaming. There's very
little actual change in semantics.

- Implement child_begin() and child_end() for AsmStmt.  Previously these had stub implementations that did not iterate over the input/output operands of an inline assembly statement.
- Use ExprIterator for performing iteration over input/output operands.

Add setSubgraphColor to color an entire portion of a SelectionDAG.  This
will be used to support debug features in TableGen.

Add STL-style typedefs and default constructors to make it possible to
use DenseMap in more contexts.

Fix PR2634.  Create new virtual registers from spills early so that we
can give it the same stack slot as the spilled interval if it is folded.
This prevents the fold/unfold code from pointing to the wrong register.

(and a bunch of other node types).  While there, I
added a doNotCSE predicate and used it to reduce code
duplication (some of the duplicated code was wrong...).
This fixes ARM/cse-libcalls.ll when using LegalizeTypes.

worklist twice: UpdateNodeOperands could morph
a new node into a node already on the worklist.
We would then recalculate the NodeId for this
existing node and add it to the worklist.  The
testcase is ARM/cse-libcalls.ll, the problem
showing up once UpdateNodeOperands is taught to
do CSE for calls.

When destroying a translation unit, deallocate its owned declarations in reverse order, because there may be dependencies among the declarations.

This simplifies debug of this particular diagnostic (and removes some code clutter).

Fix <rdar://problem/6315646> clang on xcode: error: invalid operands to binary expression ('id<NSTableViewDelegate>' and 'XCExtendedArrayController *').

There is still a bug here (as the FIXME in the test case indicates). Prior to this patch, the bug would generate an error. Now, we simply do nothing (which is less harmful until we can get it right). The complete bug fix will require changing ASTContext::mergeTypes(), which I'd like to defer for now.

For now, don't split live intervals around x87 stack register barriers. FpGET_ST0_80 must be right after a call instruction (and ADJCALLSTACKUP) so we need to find a way to prevent reload of x87 registers between them.

LargeBlockInfo, we can now dramatically simplify their implementation
and speed them up at the same time.  Now the code has time proportional
to the number of uses of the alloca, not the size of the block.

This also eliminates code that tried to batch up different allocas which
are used in the same blocks, and eliminates the 'retry list' logic which
was baroque and no unneccesary.  In addition to being a speedup for crazy
cases, this is also a nice cleanup:

a trivial dense map.  Use this in RewriteSingleStoreAlloca to
avoid aggressively rescanning blocks over and over again.  This
fixes PR2925, speeding up mem2reg on the testcase in that bug
from 4.56s to 0.02s in a debug build on my machine.
