"add{l} {$src2, $dst|$dst, $src2}",

Work towards fixing crasher with compound literals...

Before this commit, we crashed in ParseBinOp...
[dylan:~/llvm/tools/clang] admin% ../../Debug/bin/clang -parse-ast-check compound_literal.c
SemaExpr.cpp:1298: failed assertion `(rhs != 0) && "ParseBinOp(): missing right expression"'
With this commit, we still crash in the newly added action ParseCompoundLiteral (which is progress:-)
[dylan:~/llvm/tools/clang] admin% ../../Debug/bin/clang -parse-ast-check compound_literal.c

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.
