Remove locally duplicated code for calling functions in the inferior. The only differences were in the specific trap vectors used and whether or not an fpu was present. These are now handled by appropriate definitions of BPT_VECTOR and HAVE_68881 respectively. Other minor obvious cleanups. Minor spelling correction in valops.c.

of discovering this value and use it if so, and if we need it. */
