Find the structure describing a reference in REFERRING_NODE to REFERRED_NODE
   and associated with statement STMT.

struct ipa_ref* ipa_maybe_record_reference ( symtab_node  referring_node, tree  val, enum ipa_ref_use  use_type, gimple  stmt  )

read

If VAL is a reference to a function or a variable, add a reference from
   REFERRING_NODE to the corresponding symbol table node.  USE_TYPE specify
   type of the use and STMT the statement (if it exists).  Return the new
   reference or NULL if none was created.

read

Return ipa reference from REFERING_NODE or REFERING_VARPOOL_NODE
   to REFERED_NODE or REFERED_VARPOOL_NODE. USE_TYPE specify type
   of the use and STMT the statement (if it exists).
