The locations are actually false: they should include the location of
the semicolon (we print statements), but they don't.

* examples/c/glr/c++-types.test, examples/c/glr/c++-types.y,
* tests/cxx-type.at:
Fix locations and adjust expectations.
* examples/c/glr/c++-types.y: Flush stdout so that the logs (on
stderr) and the effective output (on stdout) mix correctly.
While at it, be a bit more const-correct.
* examples/c/glr/c++-types.y (node_print): New.
Use YY_LOCATION_PRINT instead of duplicating it.
And actually use it in the action instead of badly duplicating it.
(main): Add proper option support.
* examples/c/glr/c++-types.test: Adjust expectations on locations.
* examples/c++/glr/c++-types.yy: Fix bad iteration.

* data/skeletons/glr.c, data/skeletons/glr2.cc (b4_call_merger): Use
the symbol's slot, not its type.
* examples/c/glr/c++-types.y: Use explicit per-symbol typing together
with api.value.type=union.
(yylex): Use yytoken_kind_t.
Currently this example crashes on input such as "T (x) + y;".
The same example with glr.c works properly.

parses, pure, locations".
