d: Add TARGET_D_REGISTER_OS_TARGET_INFO

This allows target platforms that have D support files to defined their
own target-specific information keys.

gcc/ChangeLog:

	* doc/tm.texi: Regenerate.
	* doc/tm.texi.in (D language and ABI): Add @hook for
	TARGET_D_REGISTER_OS_TARGET_INFO.

gcc/d/ChangeLog:

	* d-target.cc (Target::_init): Call new targetdm hook to register OS
	specific target info keys.
	* d-target.def (d_register_os_target_info): New hook.
