re PR rtl-optimization/79032 (unaligned memory access generated with LRA and optimization)

PR rtl-optimization/79032
* lra-constraints.c (simplify_operand_subreg): In the MEM case, test
the alignment of the adjusted memory reference against that of MODE,
instead of the alignment of the original memory reference.
