rs6000: Clean up the pre-checkings of expand_block_compare
Remove P7 CPU test as only P7 above can enter this function and P7 LE is
excluded by the checking of targetm.slow_unaligned_access on word_mode.
Also performance test shows the expand of block compare is better than
library on P7 BE when the length is from 16 bytes to 64 bytes.

* config/rs6000/rs6000-string.cc (expand_block_compare): Assert
only P7 above can enter this function. Remove P7 CPU test and let
P7 BE do the expand.
gcc/testsuite/
* gcc.target/powerpc/block-cmp-4.c: New.
