re PR target/91604 (ICE in extract_insn at recog.c:2310 since r272323)

PR target/91604
* config/i386/i386-expand.c (split_double_mode): If there is more than
one MEM operand and they are rtx_equal_p, reuse lo_half/hi_half from
already split matching MEM operand instead of calling adjust_address
again.

* gcc.target/i386/pr91604.c: New test.
