[fortran,committed] Give Fortran-90-style names to intrinsic types

[FX Coudert]

Instead of naming the intrinsic types int4, logical4, real4, complex4  
and character, the patch above gives them a proper Fortran 90 name:  
integer(kind=4), ... and character(kind=1). This then shows up in gdb  
when inspecting the type of variables:

(gdb) ptype i
type = int(kind=4)
(gdb) ptype j
type = int(kind=8)
(gdb) ptype l
type = logical(kind=4)

This does not yet work for real and complex, because GDB ignores what  
we say there. (Time to make use of my new GDB copyright assignement!)

Regtested on x86_64-linux, committed (rev. 130261) as obvious after  
Jerry's approval on IRC.

         * trans-types.c (gfc_init_types): Use Fortran-90-style type
         names, with kinds.
