[Bug testsuite/21910] New: Files from previous runs can make some testcases fail

["e9925248 at stud4 dot tuwien dot ac dot at" <gcc-bugzilla at gcc dot gnu dot org>]

If old dump files for a testcase are left, if the name of the dump file has
changed, errors like the following occur:

ERROR: gcc.dg/tree-ssa/structopt-1.c: error executing dg-final: couldn't open
"structopt-1.c.t50.lim structopt-1.c.t53.lim": no such file or directory
UNRESOLVED: gcc.dg/tree-ssa/structopt-1.c: error executing dg-final: couldn't
open "structopt-1.c.t50.lim structopt-1.c.t53.lim": no such file or directory

Deleting all generated *.c.t* files in the testsuite directory, solves this problem.

I use dejagnu from the src-tree of sourceware.org.
