d: Merge upstream dmd, druntime c8ae4adb2e, phobos 792c8b7c1.

D front-end changes:

	- Import dmd v2.101.0.
	- Deprecate the ability to call `__traits(getAttributes)' on
	  overload sets.
	- Deprecate non-empty `for' statement increment clause with no
	  effect.
	- Array literals assigned to `scope' array variables can now be
	  allocated on the stack.

D runtime changes:

	- Import druntime v2.101.0.

Phobos changes:

	- Import phobos v2.101.0.

gcc/d/ChangeLog:

	* dmd/MERGE: Merge upstream dmd c8ae4adb2e.
	* typeinfo.cc (check_typeinfo_type): Update for new front-end
	interface.
	(TypeInfoVisitor::visit (TypeInfoStructDeclaration *)): Remove warning
	that toHash() must be declared 'nothrow @safe`.

libphobos/ChangeLog:

	* libdruntime/MERGE: Merge upstream druntime c8ae4adb2e.
	* src/MERGE: Merge upstream phobos 792c8b7c1.
