riscv: Add support for XTheadBb in string-fz[a,i].h
XTheadBb has similar instructions like Zbb, which allow optimized string processing: * th.ff0: find-first zero is a CLZ instruction. * th.tstnbz: Similar like orc.b, but with a bit-inverted result. The instructions are documented here: https://github.com/T-head-Semi/thead-extension-spec/tree/master/xtheadbb These instructions can be found in the T-Head C906 and the C910. Tested with the string tests. Signed-off-by: Christoph Müllner <christoph.muellner@vrull.eu> Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
