read operations and instead use the doubleword already readed with
bitwise operations.

e23d3d2690 PowerPC: Optimized strcmp for PPC64/POWER7
Optimization is achieved on 8 byte aligned strings with double word
comparison using cmpb instruction. On unaligned strings loop unrolling
is applied for Power7 gain.
