In the normal case (no error happens), cleanup-tree-dump will delete such files,
as a more verbose run of the testsuite shows:
Testing tree-ssa/ssa-sink-2.c
doing compile
Invoking the compiler as /tmp/gcc/host-i686-pc-linux-gnu/gcc/xgcc
-B/tmp/gcc/host-i686-pc-linux-gnu/gcc/

pid is 14380 -14380
waitres is 14380 exp6 0 0
output is

In my case, cleanup-tree-dump is not executed, as scan-tree-dump-times fails
before, because of the additonal file:
Testing tree-ssa/ssa-sink-1.c

Error/Warning threshold exceeded: 1 0 (max. 1 3)
To solve this problem, the scan-tree-* functions need to check for this case and
remove the old files, so that at least future runs will not suffer from this
problem, eg:
