[PowerPC] using milicode call for strcmp instead of lib call (#177009) 
1. AIX has "millicode" routines, which are functions loaded at boot time
into fixed addresses in kernel memory. This allows them to be customized
for the processor. The __strcmp routine is a millicode implementation;
we use millicode for the strcmp function instead of a library call to
improve performance.
