Yeah, you actually want to use "imm":
list<dag> Pattern = [(int_repeat_x_times imm:$imm)];
When the table generator sees "i64" it doesn't go looking in the
InOperandList to determine that the operand should be an immediate. It
just matches anything and shoves it into a register. It *does* know
about "imm" though because that's defined to match u...
