Subject: d: Merge upstream dmd cb49e99f8, druntime 55528bd1, phobos 1a3e80ec2.

D front-end changes:

    - Import dmd v2.099.0-beta.1.
    - It's now an error to use `alias this' for partial assignment.
    - The `delete' keyword has been removed from the language.
    - Using `this' and `super' as types has been removed from the
      language, the parser no longer specially handles this wrong code
      with an informative error.

D Runtime changes:

    - Import druntime v2.099.0-beta.1.

Phobos changes:

    - Import phobos v2.099.0-beta.1.

gcc/d/ChangeLog:

	* dmd/MERGE: Merge upstream dmd cb49e99f8.
	* dmd/VERSION: Update version to v2.099.0-beta.1.
	* decl.cc (layout_class_initializer): Update call to NewExp::create.
	* expr.cc (ExprVisitor::visit (DeleteExp *)): Remove handling of
	deleting arrays and pointers.
	(ExprVisitor::visit (DotVarExp *)): Convert complex types to the
	front-end library type representing them.
	(ExprVisitor::visit (StringExp *)): Use getCodeUnit instead of charAt
	to get the value of each index in a string expression.
	* runtime.def (DELMEMORY): Remove.
	(DELARRAYT): Remove.
	* types.cc (TypeVisitor::visit (TypeEnum *)): Handle anonymous enums.

libphobos/ChangeLog:

	* libdruntime/MERGE: Merge upstream druntime 55528bd1.
	* src/MERGE: Merge upstream phobos 1a3e80ec2.
	* testsuite/libphobos.hash/test_hash.d: Update.
	* testsuite/libphobos.betterc/test19933.d: New test.
