New Revision: 179781

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=179781
Log:
This patch reorganizes the PPH streamer sources so that all elements
streamed have the same source order in pph-streamer-out.c and
pph-streamer-in.c.

These are further set off into various sections:
    stream initialization
    primitive values
    source information
    record handling
    tree shells
    lexical elements
    vectors
    chains
    bindings
    tree aux classes
    tree base classes
    tree head and body
    file contents
    stream finalization

Removed tracing for everything but trees.  Such tracing is too verbose
for usability.

The existing tree tracing functions were asymmetric, resulting in
confusing traces.  So, I moved all of the tracing into the one
place where the tracing is effective, in the common tree write/read
functions.  All trees should now be properly traced.

The old tracing infrastructure is now dead, and will be removed in a
future patch.

File-level tracing was moved from control under the -fpph-debug flag
to the -fpph-tracer flag.

Improved template debug dumping.

Tested on x64.
