produce simple DOT graphs from SLP trees
This adds a dot_slp_tree debug function producing a simple DOT
graph from a starting node down the graph. There's no fancy
direct invocation of dot but the output is directed to a specified
file. It re-uses vect_print_slp_tree, naming nodes as their
address.

* dump-context.h (debug_dump_context::debug_dump_context):
Add FILE * parameter defaulted to stderr.
* dumpfile.c (debug_dump_context::debug_dump_context): Adjust.
* tree-vect-slp.c (dot_slp_tree): New functions.
