Incomplete patch

Fortran 2008 supports c_sizeof which is identical to gfortran's sizeof.

This patch does the following:

- Implements c_sizeof (one line in intrinsic.c)
- Fixes argument (sizeof(x) not sizeof(i)) - intrinsic.c
- Document new option  - intrinsic.texi
- trans-intrinsic.c (gfc_conv_intrinsic_sizeof): Don't create
  {
    integer(kind=8) bytes.1;
    i = 4;
  }
  in the simple case but simply "i = 4".
- simplify.c: Add gfc_simplify_sizeof:
  This partially works, is currently quite hacky and fails for substrings.

TODO: Fix the last item.
