We should make up our mind and close either this one or 23821... they are
requesting exactly opposite things.

I think this is bug is a valid request for FRE to eliminate redundant PHI
nodes:
:
# c_1 = PHI
# d_2 = PHI
D.1599_10 = c_1 + d_2;
There are no two same PHI nodes in PR23821.
I am going to fix this one.

Re-confirmed. The fix is to eliminate duplicate PHI nodes in eliminate() by
copy-propagating PHI value-numbers.
