Remove ValueManager::getRegionValueSymbolValOrUnknown().  It was just extra veneer on top of getRegionValueSymbolVal().

remove start/finishGVStub and the BufferState helper class from the
MachineCodeEmitter interface.  It has the side-effect of not setting the
indirect global writable and then executable on ARM, but that shouldn't be
necessary.

found last time.  Instead of trying to modify the IR while iterating over it,
I've change it to keep a list of WeakVH references to dead instructions, and
then delete those instructions later.  I also added some special case code to
detect and handle the situation when both operands of a memcpy intrinsic are
referencing the same alloca.

non-existing 'isa' field of a non-existing struct type
all related to legacy type definition for 'id' which we have
dropped in clang in favor of a built-in type.

on PR5610 (2.185 -> 2.130s).  The big issue is that this is making
insanely huge macro argument lists with over a million tokens in it.
The reason that mallco and free are so expensive is that we are 
actually going to the kernel to get it, and switching to a bump 
pointer allocator won't change this in an interesting way.

 - This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

If a ParmVarDecl's default argument is a CXXExprWithTemporaries, return the underlying expr instead. Add getNumDefaultArgTemporaries and getDefaultArgTemporary which returns the temporaries a default arg creates.

For hi/odd of an odd-length vector, the last component is undefined.  Since
we shuffle with an undef vector, no CodeGen needs to change to support this.

1. Use std::equal instead of reinventing it.
2. don't run dtors in destroy_range if element is pod-like.
3. Use isPodLike to decide between memcpy/uninitialized_copy 
   instead of is_class.  isPodLike is more generous in some cases.

Remove isPod() from DenseMapInfo, splitting it out to its own
isPodLike type trait.  This is a generally useful type trait for
more than just DenseMap, and we really care about whether something
acts like a pod, not whether it really is a pod.
