[Bug tree-optimization/21791] New: ccp and copy-prop print out too much garbage with -fdump-tree-ccp/copy-details

[kazu at cs dot umass dot edu]

CCP and COPY-PROP print out garbage like

Replaced x_6 = 1;
 with x_6 = 1;

Replaced <L0>:;
 with <L0>:;

The dump would look a lot nicer if they print out statements that
have been changed.
