Add list of potential target datatype comments to SYSTEM.def

Add list of potential target datatype comments to all SYSTEM.def
files to improve usefulness of target independent documentation.

gcc/m2/ChangeLog:

	* gm2-libs-coroutines/SYSTEM.def: Added list of data types.
	* gm2-libs-iso/SYSTEM.def: Added list of data types.
	* gm2-libs/SYSTEM.def: Added list of data types.
	* target-independent/SYSTEM-iso.texi: Rebuilt.
	* target-independent/SYSTEM-pim.texi: Rebuilt.
	* target-independent/gm2-libs.texi: Rebuilt.
