avoid crash with test-linearize -vv
When verbose is set to 2 or higher, show_instruction()
also display removed instructions. Some of these instructions
can have their associated symbol removed and set to NULL
which will cause a crash with 'test-linearize -vv'.
Fix this by avoiding to dereference symbol's details of
removed instructions.
