constant nodes with vector types. Also teach the asm printer how to print
ConstantPacked constant pool entries. This allows us to generate altivec
code such as the following, which adds a vector constantto a packed float.

For the llvm code:

entry:
%tmp1 = load <4 x float> * %a;
%tmp2 = add <4 x float> %tmp1, < float 0.0, float 0.0, float 0.0, float 1.0 >
store <4 x float> %tmp2, <4 x float> *%a
ret void
