New revision which can also be compiled with GCC 4.8.

Ensure dump_template_decl for function templates never prints template
parameters after the function name (it did with -fno-pretty-templates)
and skip output of irrelevant & confusing "[with T = T]" in
dump_substitution.
gcc/cp/ChangeLog:
PR c++/100716
* error.c (dump_template_bindings): Include code to print
"[with" and ']', conditional on whether anything is printed at
all. This is tied to whether a semicolon is needed to separate
multiple template parameters. If the template argument repeats
the template parameter (T = T), then skip the parameter.
This description should really be in a comment in the code, rather than
the ChangeLog. OK either way.
(dump_substitution): Moved code to print "[with" and ']' to
dump_template_bindings.
(dump_function_decl): Partial revert of PR50828, which masked
TFF_TEMPLATE_NAME for all of dump_function_decl. Now
TFF_TEMPLATE_NAME is masked for the scope of the function and
only carries through to dump_function_name.
(dump_function_name): Avoid calling dump_template_parms if
TFF_TEMPLATE_NAME is set.
gcc/testsuite/ChangeLog:
PR c++/100716
* g++.dg/diagnostic/pr100716.C: New test.
* g++.dg/diagnostic/pr100716-1.C: Same test with
-fno-pretty-templates.
