of do_children_tests.

* gdb.mi/mi-var-cmd.exp: Step to right line of
do_locals_tests.
(do_children_tests): User char[2] instead of
char so that automatic printing of pointers to char
don't give unpredicable result.
* gdb.mi/mi2-var-cmd.exp: Likewise.
* lib/mi-support.exp (mi_continue_to_line):
Pass test name to mi_wait_for_stop.
Fetch varobj values from memory in a single place,
and only fetch the values that are really needed.
* varobj.c (struct varobj): Clarify comment.
(my_value_equal): Remove.
(install_new_value): New function.
(type_of_child): Remove.
(varobj_create): Use install_new_value.

stopping places.
* gdb.base/fileio.exp: Breakpoint stop function and remove
explicit line number references.
* gdb.cp/m-static.cc (main): Write to test4.dummy, so that test4
is allocated by the compiler.
* gdb.mi/var-cmd.c: (do_special_tests): Write to u, anonu, s,
anons, e, anone to force their allocation by the compiler.
* gdb.mi/mi-stack.c: New file, based on gdb.mi/basics.c.
