VMEMOPREG macros are deprecated in row.h

Usage examples
    VMEMOPREG(vpavgb,0x00,0,4,1,ymm0,ymm0)     // vpavgb (%0,%4,1),%%ymm0,%%ymm0
    VMEMOPREG(vpavgb,0x20,0,4,1,ymm1,ymm1)

Regular expressions to remove MEMACCESS macros:

VMEMOPREG\((.*),(.*),(.*),(.*),(.*),(.*),(.*)\)(.*)(//.*)
"\1    \2(%\3,%\4,\5),%%\6,%%\7      \\n"

VMEMOPREG\((.*),(.*),(.*),(.*),(.*),(.*),(.*)\)
"\1    \2(%\3,%\4,\5),%%\6,%%\7            \\n"
