I switch to letting proc exec_cmd_expect_vCont_count return 0 or 1 to
indicate the test pass or not, and skip the rest if it returns 1 in
the test. How about this below?

* gdb.base/range-stepping.exp: Skip the rest of tests if the
test fails.
* lib/range-stepping-support.exp (exec_cmd_expect_vCont_count):
Return 0 if the test passes, otherwise return 1.
