When testing gdb.base/skip-inline.exp using clang, we get failures when trying to step out of functions, since clang requires one fewer step when compared to gcc. The inferior gets increasingly out of sync as the test continues because of this difference, which generates those failures. This commit fixes this by switching those hardcoded steps to gdb_step_until, to guarantee that the inferior is always synced to what the test expects. This approach does not work for the parts that use step 2 or step 3, so when we identify that clang is being used, those tests are skipped.
