[PATCH] Support no newline in print_gimple_stmt

[Martin Liška]

I've just noticed that tree-ssa-dse wrongly prints a new line to dump file.
For the next stage1, I'll go through usages of print_gimple_stmt and remove
extra new lines like:

gcc/auto-profile.c:      print_gimple_stmt (dump_file, stmt, 0, TDF_SLIM);
gcc/auto-profile.c-      fprintf (dump_file, "\n");

Patch can bootstrap on ppc64le-redhat-linux and survives regression tests.

Ready to be installed?
Martin
