Use string concatentation operator (#) instead of !strconcat, which is a lot more readable.
Added block load and store patterns.  Basic vector operations working:

	%0 = alloca <16 x i32>
	%1 = alloca <16 x i32>
	%x = load <16 x i32>* %0
	%y = load <16 x i32>* %1
	%2 = add <16 x i32> %x, %y
	store <16 x i32> %2, <16 x i32>* %0

Compiles to:

	v0 = mem_l[s29 - 128]
	v1 = mem_l[s29 - 64]
	v0 = v1 + v0
	mem_l[s29 - 64] = v0
