[patch/testsuite/cp] kill supports_template_debugging

[mec dot gnu at mindspring dot com (Michael Elizabeth Chastain)]

This patch removes the test suite symbol 'supports_template_debugging'.

This symbol was always defined if __cplusplus is defined, so it doesn't
actually say anything useful.  It's used in just one place,
gdb.cp/templates.exp, which tests it *after* trying to compile a C++ file
with template support.  Hey, if the compiler being tested can compile
templates.cc, then gdb ought to take a shot at debugging it!

Tested on native i686-pc-linux-gnu with gcc 2.95.3 and gcc 3.3.2,
dwarf-2 and stabs+.

I am committing this now.

Good-bye to one more bit of cruft we don't need.

Michael C
