GCC toplev.c uses ASM_OUTPUT_ALIGNED_DECL_COMMON with a NULL decl to
emit the LTO marker, so the rs6000 implementation needs to test for
that situation.  config/darwin.c tests similarly.  With this patch,
gcc -flto produces correct output on AIX.

Bootstrapped on powerpc-ibm-aix7.2.0.0

Thanks, David

* config/rs6000/rs6000.c
(rs6000_xcoff_asm_output_aligned_decl_common): Test for NULL decl.
