Commit 67360decc3d4bda363c2fa2550eb1c2b876c8cf0 by eschweitz
[flang][fir] Add array value operations.

We lower expressions with rank > 0 to a set of high-level array operations.
These operations are then analyzed and refined to more primitve
operations in subsequent pass(es).

This patch upstreams these array operations and some other helper ops.
