* config/tc-i386.c (md_assemble): Force number of displacement
operands to zero when processing string instruction.
(i386_index_check): Special-case string instruction operands. Don't
fudge address prefix if there already was a memory operand. Fix
error message to correctly reflect the addressing mode used.
(i386_att_operand): Fix comment.
(i386_intel_operand): Snapshot, clear, and restore base and index
reg for each operand processed. Increment count of memory operands
later.
