The dlmzb. instruction requires an 8-byte aligned operand. The testcases
try to enforce that by passing an arg as "long long *", but current GCC
still assumes an alignment of 1 (correctly I think -- the pointer is only
used as pointer to char).
This patch changes the testcases to explicitly have an 8-byte aligned datum.
Okay for mainline?

* gcc.target/powerpc/405-dlmzb-strlen-1.c: Explicitly align arg.
* gcc.target/powerpc/440-dlmzb-strlen-1.c: Ditto.
