c++: More cleanups for modern C++
Here are some more places where we can declare variables at the
assignment point, rather than use C89. Also, let's name our variables
by what they contain -- the register allocator is perfectly able to
track liveness for us.
gcc/cp/
* decl.c (decls_match): Move variables into scopes
they're needed in.
(duplicate_decls): Use STRIP_TEMPLATE.
(build_typename_type): Move var decls to their assignments.
(begin_function_body): Likewise.
* decl2.c (get_guard): Likewise.
(mark_used): Use true for truthiness.
* error.c (dump_aggr_type): Hold the decl in a var called
'decl', not 'name'.
