[PATCH] Introduce gcc::dump_manager class


When repeatedly compiling within one process, the dumpfile numbering
doesn't reset, leading to dumpfiles after the initial ones having
unpredictable numbers like here (-fdump-tree-all at -O0):
    
      fake.c.000i.cgraph
      fake.c.004t.gimple
      fake.c.1477t.omplower
      fake.c.1478t.lower
      (etc)
    
Note the large (and increasing) leap in the numbering from the base
dumpfiles which get consistent numbering (000, 004 here) to the
autonumbered ones (1477 in this example).  This was due to this implicit
state within dump_register:
    
      static int next_dump = FIRST_AUTO_NUMBERED_DUMP;
      int num = next_dump++;

messing up the numbering on subsequent in-process creation of passes.

This patch introduces a new gcc::dump_manager class to hold such state,
with a singleton owned by the gcc::context, fixing the inconsistent
dumpfile numbering.
    
Specifically, the following variables from dumpfile.c are moved from
being statically allocated to being fields of gcc::dump_manager (gaining
"m_" prefixes):
    
      * next_dump
      * extra_dump_files
      * extra_dump_files_in_use
      * extra_dump_files_alloced

Potentially other aspects of dumping could be moved here, but this
seemed like a logically self-contained change.

Successfully bootstrapped and regtested on x86_64-unknown-linux.

OK for trunk?
