[testsuite] Inline-on-trees problem

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

Compiling this testcase with -O1 or -O2 will consume a lot of memory, a lot
of time and then crash.
id->fns protection against recursion in expand_call_inline seems to work
(optimize_function exits for all four functions), so I don't know yet why it
expands things indefinitely.
This bug e.g. prevents compiling Octave with current gcc.
