i386: Use offsetable address constraint for double-word memory operands
Double-word memory operands are accessed as their high and low part, so the
memory location has to be offsettable. Use "o" constraint instead of "m"
for double-word memory operands.
gcc/ChangeLog:
* config/i386/i386.md (*insvdi_lowpart_1): Use "o" constraint
instead of "m" for double-word mode memory operands.
(*add<dwi>3_doubleword_zext): Ditto.
(*addv<dwi>4_doubleword_1): Use "jO" constraint instead of "jM"
for double-word mode memory operands.
