In cp/error.c, I separate the initialization of the diagnostic context
from the initialization of the scratch pretty-printer (cxx_pp). This
was suggested by Gabriel in the last review of the patch and now I
realize it was a good idea. Now cxx_initialize_diagnostics is the
equivalent version of c_initialize_diagnostics. To avoid having to
make extern a bunch of functions, I moved it from cp-objcp-common.c to
error.c.
I moved the setting of diagnostic_format_decoder (global_dc) =
c_tree_printer, from c_objc_common_init to c_initialize_diagnostics,
and right after c_common_diagnostics_set_defaults. This
mimics what is done in cxx_initialize_diagnostics.
Moreover, in both c_initialize_diagnostics and
cxx_initialize_diagnostics, the FE-specific pretty-printer is
initialized first and then other settings are applied. This does not
make a difference right now, but if in the future one wishes to touch
something in the pretty-printer, it will not get overriden
immediately.
In fact, the code I removed in c_common_initialize_diagnostics, which
sets line_cutoff to 80, is useless because the pretty-printer created
here is actually never used, but overriden by the FE-specific
pretty-printers. This also means that doc/invoke.texi was wrong.
Finally, it is useless to set the maximum line length to 0 in the
constructor of cxx_pretty_printer. It is the default anyway.

This option, which is enabled by default, causes the preprocessor to warn
when a string or character literal is followed by a ud-suffix which does
not begin with an underscore. According to [lex.ext]p10, this is
ill-formed.
Also modifies the preprocessor to treat such ill-formed suffixes as separate
preprocessing tokens. This is consistent with the Clang front end (see
http://llvm.org/viewvc/llvm-project?view=rev&revision=152287), and enables
backwards compatibility with code that uses formatting macros from
<inttypes.h>, as in the following code block:
int main() {
int64_t i64 = 123;
printf("My int64: %"PRId64"\n", i64);
}
