[LLVMdev] allocating an array

If the array element type is i32 (like the size
field), then you may as well use an alloca i32;
if you use an alloca i8 then you would have to
use 4*%n rather than %n in order to get the right
amount of memory.

(did some manual optimizations on this code, as my front end generates
really dumb code)
So I need...
