d: Make TARGET_D_MINFO_SECTION hooks in elfos.h the language default.

Removes the last of all TARGET_D_* macro definitions in common target
headers.  Now everything is either defined in the D language front-end,
or D-specific target headers.

gcc/ChangeLog:

	* config/darwin-d.cc (TARGET_D_MINFO_START_NAME): Rename to ...
	(TARGET_D_MINFO_SECTION_START): ...this.
	(TARGET_D_MINFO_END_NAME): Rename to ...
	(TARGET_D_MINFO_SECTION_END): ... this.
	* config/elfos.h (TARGET_D_MINFO_SECTION): Remove.
	(TARGET_D_MINFO_START_NAME): Remove.
	(TARGET_D_MINFO_END_NAME): Remove.
	* config/i386/cygwin-d.cc (TARGET_D_MINFO_SECTION): Remove.
