Subject: [patch] Display Fortran strings in backtraces

Hi,

for Fortran it fixes displaying normal strings also in frames/backtraces:

(gdb) frame
#0  f (s=..., _s=3) at ./gdb.fortran/fortran-frame-string.f90:24
->
#0  f (s='foo', _s=3) at ./gdb.fortran/fortran-frame-string.f90:24

The patch is simple and I do not see why it should not be this way.

For C/C++ TYPE_CODE_STRING is not used.  I am not aware of Pascal but that
language is currently not really much supported in GDB anyway.

This was a part of my archer/jankratochvil/vla branch but it is not a part of
the Intel VLA patchset as it in fact is completely unrelated to "VLA".

No regressions on {x86_64,x86_64-m32,i686}-fedora22pre-linux-gnu.

Thanks,
Jan
