true), and casts make me nervous and are verbose anyway, so here's a
ConstantInt::getSigned(Ty, int64_t) method. Just overloading
ConstantInt::get() to take an int64_t too would cause ambiguous
overload errors."

Patch by Jeffrey Yasskin!

Add a VarDecl parameter to the CXXTemporaryObjectExpr constructor. It's unused for now, so no functionality change yet. Also, create CXXTempVarDecls to pass to the CXXTemporaryObjectExpr ctor.

Move the CXXConstructExpr before the CXXTemporaryObjectExpr so that the temporary object expr can inherit from the construct expr. No functionality change.

ISD::VECTOR_SHUFFLE now stores an array of integers representing the shuffle
mask internal to the node, rather than taking a BUILD_VECTOR of ConstantSDNodes
as the shuffle mask.  A value of -1 represents UNDEF.

In addition to eliminating the creation of illegal BUILD_VECTORS just to 
represent shuffle masks, we are better about canonicalizing the shuffle mask,
resulting in substantially better code for some classes of shuffles.

A clean up of x86 shuffle code, and some canonicalizing in DAGCombiner is next.

 - Otherwise, we will end up with stray .dSYM files which don't get
   lipo'ed or removed.

 - Ideally we would run dsymutil on the result, but we don't have the
   infrastructure for that yet. Note that gcc doesn't handle this case
   either.

 - <rdar://problem/6809621> [driver] clang leaves .dSYM files lying
   around in tmp.

the cast of an EXTRACT_ELEMENT with a BUILD_PAIR operand, for the
common case.

Several changes here:
1. We change Type::isIncompleteType to realize that forward declared 
   interfaces are incomplete.  This eliminate special case code for this
   from the sizeof path, and starts us rejecting P[4] when P is a pointer
   to an incomplete interface.
2. Explicitly reject P[4] when P points to an interface in non-fragile ABI
   mode.
3. Switch the sizeof(interface) diagnostic back to an error instead of a 
   warning in non-fragile abi mode.

Eliminate Sema::ObjCImplementations, relying instead on name lookup. What's good for uniformity is good for PCH (or is it the other way around?). 

As part of this, make ObjCImplDecl inherit from NamedDecl (since
ObjCImplementationDecls now need to have names so that they can be
found). This brings ObjCImplDecl very, very close to
ObjCContainerDecl; we may be able to merge them soon.

their own namespace (IDNS_Protocol) and use the normal name-lookup
routines to find them. Aside from the simplification this provides
(one less DenseMap!), it means that protocols will be lazily
deserialized from PCH files.

Make the code size of the selector table block match the code size of
the type and decl blocks.

Make BinOps typed and require a type specifier for !nameconcat.  This
allows binops to be used in typed contexts such as when passing
arguments to classes.
