[Bug rtl-optimization/20412] [4.0/4.1 Regression] RTL checking failure in the combiner

Hmm, we are simplifing the following RTL:
(compare:CC (ne:SI (reg:SI 131)
            (const_int 0 [0x0]))
        (const_int 0 [0x0]))

To:
(reg:SI 131)

Which is wrong (but I should note that simplify_set for compare does not handle reg RTL).
