gcc/
* doc/tm.texi (Misc): Document TARGET_INVALID_PARAMETER_TYPE,
TARGET_INVALID_RETURN_TYPE, TARGET_PROMOTED_TYPE, and
TARGET_CONVERT_TO_TYPE.

(TARGET_CONVERT_TO_TYPE): Define.
(TARGET_INITIALIZER): Update for new fields.
* c-decl.c (grokdeclarator): Check targetm.invalid_return_type.
(grokparms): Check targetm.invalid_parameter_type.
* c-typeck.c (default_conversion): Check targetm.promoted_type.
* c-convert.c (convert): Check targetm.convert_to_type.
