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.
