[codegen] change operand type from bool to iflag for iadd carry variants

ryzokuken · ryzokuken · commit 4d9f584b0c8a · 2019-09-04T17:27:51.000+05:30
The type of the carry operands for the carry variants of the iadd
instruction (iadd_cin, iadd_cout, iadd_carry) was bool for compatibility
reasons for isa/riscv. Since support for these instructions on RISC
architectures has been temporarily suspended, we can safely change the
type to iflags.
