In fact here we should have a register range (e.g., -mirq-ctrl-saved=r0-r9).

Blink (r31) and lp_count (r60) are special registers. The range can go from r0
up to r29. Thus, the option is a sequence made of a register range starting
with r0 to r29, and optional two individual registers: blink (r31) and lp_count
(r60). Hence, such an option looks like this:
-mirq-ctrl-saved=r0-r29,blink,lp_count
