I might be wrong, but I don't remember us changing anything in this
area. "next/step" behavior is really determined by the line info
generated by the compiler.  If the compiler was changed from not
generated a line entry for the __asm__ blocks, and now does, then
it'll change GDB's behavior.  If next/step behavior testing is
important to the testcase, then it would seem to make sense to
convert the testcase to using an assembly file instead.
