[D] Support D style sizeof and typeof expressions.

gdb/ChangeLog:

	* d-exp.y: (UnaryExpression): Support `type.sizeof' expressions.
	(PostfixExpression): Support `expr.sizeof' expressions.
	(PrimaryExpression): Support `typeof(expr)' expressions.

gdb/testsuite/ChangeLog:

	* gdb.dlang/properties.exp: New file.
