Approved by Jim Blandy:

* values.c (value_fn_field): Add physname variable. Use a minimal
symbol if we don't find a full symbol. Remove setting of the new
value's type since that was already done by allocate_value().
Remove obsolete commented out error call since callees need to
handle a NULL return, which is possible result not an error.
* eval.c (evaluate_subexp_standard): Move check for inlined
functions to precede attempt to dereference a NULL argvec[0].
