would result in calling realloc() on a null pointer.  Instead, if we encounter
this situation, make a normal call to malloc().

This allows us to compile this:

struct abc { char A; double D; };

int foo() {
  return sizeof(struct abc);
  return __alignof__(struct abc);
}

Into:

        ret i32 16
        ret i32 8

First round of extended vector support. Here is an overview...

- added ocu_vector_type attribute, Sema::HandleOCUVectorTypeAttribute(). 
- added new AST node, OCUVectorType, a subclass of VectorType.
- added ASTContext::getOCUVectorType.
- changed ASTContext::convertToVectorType() to ASTContext::getVectorType(). This is 
unrelated to extended vectors, however I was in the vicinity and it was on my todo list.
Added a FIXME to Sema::HandleVectorTypeAttribute to deal with converting complex types.

hooked up to anything, so it's not very useful yet.

alignment is equal to the stack alignment.

Note: FastDSE now equals or exceeds the results of old DSE on all of SPEC2000 and SPEC2006. Unless major problems
show up in the testers, it will likely completely replace old DSE in the near future.

Don't use * in XFAIL line unless you want it to XFAIL on everything. I don't believe you can use true regular expressions here. It will just look for those keywords. Please test this on sparc and see if they still are xfailed.

Missed the case where alloca is used but the stack size (not including callee-saved portion) is zero. Thanks Dan.

just always use strtod.  This is temporary code anyway.

Move tests that have C/C++ sources into the appropriate directory. This
allows them to be selected for testing based on whether llvm-gcc is
present or not.

Change dyn_cast for reference types to be more like pointers and not need the canonical type. Also fix so that we're not expecting a return value from a void function
