[Obvious][AArch64 Testsuite] Fix comments in vldN_lane_1.c

[Alan Lawrence]

The comments in vldN_lane_1.c say it is testing vld{1,2,3}{,q}_dup. This is 
wrong, it is testing vld{1,2,3}{,q}_lane, as per test filename; I've pushed the 
attached as  r222148.

gcc/testsuite/ChangeLog:
        gcc.target/aarch64/vldN_lane_1.c: Correct dup->lane in comments.
