[wiki, PATCH] Correct description of coarray support and remove some items from the unsupported list

[Andre Vehreschild <vehre at gmx dot de>]

Hi all,

I tried to update:

https://gcc.gnu.org/wiki/Fortran2008Status

but am not allowed to. So attached is the diff and full new page for review and
upload by whoever is allowed to do so.

  There is a large overlap with the '''No''' items in the table above.
  
-   * Parallel execution: Coarrays
- 
   * The DO CONCURRENT construct provides a means for the program to specify that individual loop iterations have no interdependencies.
  
   * The maximum rank has been increased to 15.
  
-  * An allocatable component can be of recursive type.
- 
   * Subscripts and nested implied-do limits inside a data-implied-do can be any constant expression instead of being limited to combinations of constants, implied-do variables, and intrinsic operations.
  
   * A FORALL index variable can have its type and kind explicitly declared within the construct.
  
   * A structure constructor can omit the value for an allocatable component.
  
-  * SOURCE= in an ALLOCATE statement can give an array variable the bounds as well as the value of an expression.
- 
   * The real and imaginary parts of a complex entity can be accessed independently with a component-like syntax.
  
-  * Intrinsic assignment to an allocatable polymorphic variable is allowed.
- 
   * A pointer function reference can denote a variable in any variable definition context.
  
   * Some restrictions on the use of dummy arguments in elemental subprograms have been removed.
