[PATCH] testsuite: Explicitly enable cselim pass for cselim-2.c

[Dimitar Dimitrov]

The cselim pass is enabled only for targets that have conditional move
instructions.  Since pru-unknown-elf doesn't have such instructions, the
pass is not executed, and the test fails with:

  gcc.dg/tree-ssa/cselim-2.c: dump file does not exist
  UNRESOLVED: gcc.dg/tree-ssa/cselim-2.c scan-tree-dump cselim "if-then-else 
store replacement: 3"

Fix by explicitly enabling the cselim pass for this test.

Ok for trunk?

gcc/testsuite/ChangeLog:

        * gcc.dg/tree-ssa/cselim-2.c: Pass -ftree-cselim option.
