/* This testcase checks if combine tries to combine sequences where the last
insn has a clobber of a reg, and a previous insn sets that reg.
In this case, we have three insns
(set flags (compare a b))
(set tmp (eq flags 0))
(parallel [(set dst (neg tmp))
(clobber flags)])
Previously, combine would not try the three-insn combination because of
the set and clobber of flags. Now it does. Test that. */
