Re: [Patch, Fortran] PR34514 - prevent double initialization and dimension changes after initialization

It is completely unclear what value "n" has after:

  integer :: n = 4
  dimension :: n(3)


similarly invalid is: integer :: n = 5 parameter (n = 7)

This patch adds checks to reject this.

Please try to come up with things which should be rejected; I think
there are none, but I still might have missed something.  ;-)

Build and regtested on x86-64. OK for the trunk?

PS: I did not check the standard, but ifort and NAG f95 reject it. As it
makes sense, I believe these compilers. If needed be, I can still try to
find it in the standard.

OK to commit
