[Bug translator/5690] New: optimize more unused arrays

Consider the following script:
global foo
probe begin { foo[1] = 2 }
probe end { delete foo }
Then the "foo" array should be elided, since it is only
ever written to but not read. (But see bug #5686, which
would kick in with an extra flag and override this behavior.)
