[flang] Inline minval/maxval over elemental/designate (#103503)
This PR intends to optimize away `hlfir.elemental` operations, which
leave temporary buffers (`allocmem`) in FIR. We typically see elemental
operations in the arguments of reduction intrinsics, so extending
`OptimizedBufferization` shall be the first solution to get heap-free
code.
Here we newly handle `minval`/`maxval` along with other reduction
intrinsics. Those functions over elemental become do loops. Furthermore,
we take the same action with `hlfir.designate` in order to inline more
intrinsics, which otherwise call runtime routines.
