Introduce a syntax for marking operands as "optional use"
Introduce a syntax to mark an operand that is not always used when
an instrution is executed. Example of such operands are the fail
label for is_nil or the number of live registers for an
allocate instruction.
Use a question mark to annotate optional use:
is_nil f? xy
allocate t t?
