* coffread.c (process_coff_symbol): Change PCC argument correction

so that it only happens on big-endian targets; so that it only
happens if the short or char argument is aligned on an int
boundary; and so that it changes the location, rather than the
type, of the argument.  These changes tend to parallel similar
(old) changes in stabsread.c.

* coffread.c (coff_read_enum_type):  Use the specified size for
enums, don't assume that they are int-sized.

* c-valprint.c (c_val_print):  Don't assume enums are the same as
ints.
