Without any optimization or when it cannot be optimized before
bufferization, an hlfir.elemental lowers to an array temporary.
Its codegen consists in:

- allocating a temp given the type, shape, and length parameter arguments.
- generating a loop nest given the elemental shape
- inlining the body of the elemental inside the loops, and replacing the yield_element by an assignment to an element of the temp.
