This allows building the compiler builtins library for the Armv8-M Baseline architecture. It can be built in the same way as other baremetal targets using the appropriate '--target' flag (e.g. --target=armv8m.base-eabi). NOTE: As with the other Cortex-M targets, only the builtins library is supported. There is no support for sanitizers, etc. The armv8m.base architecture is a superset of armv6m, so adding it to the cmake files using thumb1_SOURCES is almost enough for it to compile. Minor changes are needed to divsi3 and udivsi3, because armv8m.base does have support for div instructions but not mov with an immediate operand.
