2e53a68c - [flang][runtime] Speed up initialization & destruction (#148087)

[flang][runtime] Speed up initialization & destruction (#148087) Rework derived type initialization in the runtime to just initialize the first element of any array, and then memcpy it to the others, rather than exercising the per-component paths for each element. Reword derived type destruction in the runtime to detect and exploit a fast path for allocatable components whose types themselves don't need nested destruction. Small tweaks were made in hot paths exposed by profiling in descriptor operations and derived type assignment.
