Extract the inline asm operand reorder/remap logic into a dedicated helper so `print_inline_asm` stays focused on assembling the printed argument list. This keeps the reordered-template logic local to the AST pretty printer while making the main printing path easier to read. Also extend the pretty regression test with a `const` operand case. That checks that non-register operands other than `in(reg)` are also moved ahead of explicit register operands and that the remapped template indices still match the new operand order.
