d: Merge upstream dmd 609c3ce2d, phobos 3dd5df686

Browse source 
D front-end changes:

 - Contracts for pre- and postconditions are now implicitly "this"
   const, so that state can no longer be altered in these functions.

 - Inside a constructor scope, assigning to aggregate declaration
   members is done by considering the first assignment as initialization
   and subsequent assignments as modifications of the constructed
   object.  For const/immutable fields the initialization is accepted in
   the constructor but subsequent modifications are not.  However this
   rule did not apply when inside a constructor scope there is a call to
   a different constructor.  This been changed so it is now an error
   when there's a double initialization of immutable fields inside a
   constructor.

Phobos changes:

 - Don't run unit-tests for unsupported clocks in std.datetime.  The
   phobos and phobos_shared tests now add -fversion=Linux_Pre_2639 if
   required.

 - Deprecate public extern(C) bindings for getline and getdelim in
   std.stdio.  The correct module for bindings is core.sys.posix.stdio.
