* infcall.c (call_function_by_hand): Delete variable
"n_method_args". Localize "param_type"'s declaration to the loop
that it is used. Reinstate code assigning to said variable -
deleted on 2002-06-14. Rationalize calls to value_args_coerce.
Rationalize code using "param_type".
* infcall.c (call_function_by_hand): Use new variable "bp_addr" to
compute the breakpoint address. Only call FIX_CALL_DUMMY when
ON_STACK. Eliminate the variable "addr". Do not pass "real_pc"
to DEPRECATED_PUSH_RETURN_ADDRESS.
