Fix PR debug/14638

* tree.h (DECL_DEBUG_ALIAS_OF): New macro.
* var-tracking.c (track_expr_p): Don't disqualify tracking of variables
that are aliases of variables we want to track, unless the
original variable is also ignored for debugging purposes.
(VARIABLE_HASH_VAL): Use DECL_UID, so that this is deterministic.
  * tree-outof-ssa.c (create_temp): Note who we are a debug alias of.
* dwarf2out.c (dwarf2out_var_location): Add us to the location of
the decl we are an alias of.
