x86: Remove low-level lock optimization
The current approach is to do this optimizations at a higher level, in generic code, so that single-threaded cases can be specifically targeted. Furthermore, using IS_IN (libc) as a compile-time indicator that all locks are private is no longer correct once process-shared lock implementations are moved into libc. The generic <lowlevellock.h> is not compatible with assembler code (obviously), so it's necessary to remove two long-unused #includes. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
