If
(plus:DI (plus:DI (zero_extend:DI (unspec:SI [
(const_int 0 [0])
] UNSPEC_TP))
(reg:DI 97))
(reg:DI 2 cx [orig:98 D.1709 ] [98]))
leads to reload problem, shouldn't we simply not generate
(zero_extend:DI (unspec:SI [(const_int 0 [0])] UNSPEC_TP))
to begin with, given that OS provides
(unspec:DI [(const_int 0 [0])] UNSPEC_TP)
