The ARC EM family processors do not support native atomic assembly
instructions (LLOCK and SCOND). Therefore, the assembly version
of atomic functions cannot be used. This adds pure C version of
these atomic functions.

Saves an errno per-thread, retrieved via _get_errno(), instead of
changing the value of a global variable during context switches to avoid
a hit to the context switch performance.
Per-arch asm implementations are provided for maximum performance.
Enabled by default, but can be disabled via the CONFIG_ERRNO option.

The inline versions are renamed to remove the _inline suffix, and the
non-inline versions are removed from the code base.

One of many steps in the transform BSPs to platforms work item. At the end
of this work item, there should not be any code in the 'arch/arc' directory.
