rs6000: Correct definition of macro of fixed point efficient unaligned
Marco TARGET_EFFICIENT_OVERLAPPING_UNALIGNED is used in rs6000-string.cc
to guard the platform which is efficient on fixed point unaligned
load/store. It's originally defined by TARGET_EFFICIENT_UNALIGNED_VSX
which is enabled from P8 and can be disabled by mno-vsx option. So the
definition is improper. This patch corrects it and call
slow_unaligned_access to judge if fixed point unaligned load/store is
efficient or not.

* config/rs6000/rs6000.h (TARGET_EFFICIENT_OVERLAPPING_UNALIGNED):
Remove.
* config/rs6000/rs6000-string.cc (select_block_compare_mode):
Replace TARGET_EFFICIENT_OVERLAPPING_UNALIGNED with
targetm.slow_unaligned_access.

(expand_block_compare): Likewise.
