Add ability to use optimized versions of string functions for ARCv3 32-bit
CPUs with UCLIBC_HAS_STRING_ARCH_OPT option. Add optimized
memcpy/memset/memcmp code for ARCv3 CPUs based on the code from newlib
and adapt for ARCv3 existed optimized strchr/strcmp/strcpy/strlen.
Link to the Synopsys newlib repo with code for ARCv3 on GitHub:

New ARCv3 ISA includes both 64-bit and 32-bit CPU family.
This patch adds support for 32-bit ARCv3 HS5x processors.

Add a header file with assembler macros to be able to handle in one
place the differences between ARCv2 and ARCv3 ISAs. It is a preparatory
step before the introduction of support for ARCv3 CPUs.
