Assuming I understand what is going here: Would it be possible to add a special case InlineAsm instruction and basically replace the "`// Allocate virtreg uses and insert reloads as necessary.`" loop with a 2-pass algorithm that first assign non-foldable operands and in a 2nd pass over the operands the foldable ones?
