i386: Zhaoxin yongfeng enablement
Enable -march/-mtune=yongfeng. Costs and tunings are set according
to the characteristics of the processor. Add a new .md file to describe
yongfeng processor.
gcc/ChangeLog:
* common/config/i386/cpuinfo.h (get_zhaoxin_cpu): Recognize yongfeng.
* common/config/i386/i386-common.cc: Add yongfeng.
