This patch forms part of the ARMv8-M Baseline/Mainline support, adding Clang targeting for ARMv8-M Baseline/Mainline.

ARMv8-M Mainline is a superset of ARMv7-M, containing all ARMv7-M instructions plus ARMv8-A semaphores and atomics and the ARMv8-M security extensions.

ARMv8-M Baseline is a superset of ARMv6-M, containing all ARMv6-M instructions plus ARMv8-A semaphores and atomics, ARMv7-M exclusives, various code optimization instructions (wide branches, CBZ, hardware divide), MOVW/MOVT and the ARMv8-M security extensions.
