Ensure that dump calls are guarded with dump_enabled_p 

If called when !dump_enabled_p, the dump_* functions effectively do
nothing, but as of r263178 this doing "nothing" involves non-trivial
work internally.

I wasn't sure whether the dump_* functions should assert that
  dump_enabled_p ()
is true when they're called, or if they should bail out immediately
for this case, so in this patch I implemented both, so that we get
an assertion failure, and otherwise bail out for the case where
!dump_enabled_p when assertions are disabled.

The patch also fixes all of the places I found during testing
(on x86_64-pc-linux-gnu) that call into dump_* but which
weren't guarded by
  if (dump_enabled_p ())

gcc/ChangeLog:
	* dumpfile.c (VERIFY_DUMP_ENABLED_P): New macro.
