RISC-V: add zbb support to string functions
Add handling for ZBB extension and add support for using it as a
variant for optimized string functions.
Support for the Zbb-str-variants is limited to the GNU-assembler
for now, as LLVM has not yet acquired the functionality to
selectively change the arch option in assembler code.
This is still under review at
