It was written this way as it has semantical logic - how the type is
determined depends on TYPE_CODE_* of that object.  Just accidentally in this
case it is the same.  I do not do performance micro-optimizations which
compiler will do anyway.  But I have changed it.

Yes, fixed.  (Not discussing the 72 vs. 78 or 80 or which width of comments
rule.)

It is "inferior NULL", so I find that "NULL" valid there.

Done although I have added line "Otherwise it is zero." there:

+  /* Inferior parameter out value type or NULL if the inferior function does not
+     have one.  */
+  struct type *out_value_type;
+
+  /* If the inferior function has an out value, this is its address.
+     Otherwise it is zero.  */
+  CORE_ADDR out_value_addr;


Without that line 'out_value_addr' would be unspecified if out_value_type is
NULL which does not correspond to the current code.
