[RFA] dwarf2read.c: Use make_function_type instead of lookup_function_type

Hi,

the below patch uses make_function_type instead of lookup_function_type
in read_subroutine_type.  The reason is that it's important that `ftype'
is a new type structure for each function and so it shouldn't get reused
by other function types.  The comment for lookup_function_type indicates
that it's made to do exactly that, reusing already existing function
types as they fit.  That's not implemented so far, but it might happen
at one point, so I suggest to switch to make_function_type in
read_subroutine_type before something weird happens.

Ok to check in?
