* target.def (addr_space): Add new diagnose_usage to hook vector.
* targhooks.c (default_addr_space_diagnose_usage): Add default
implementation and...
* targhooks.h (default_addr_space_diagnose_usage): ... its prototype.
* c/c-parser.c (c_lex_one_token) [CPP_NAME]: If the token
is some address space, call targetm.addr_space.diagnose_usage.
* doc/tm.texi.in (Named Address Spaces): Add anchor for
TARGET_ADDR_SPACE_DIAGNOSE_USAGE documentation.
* doc/tm.texi: Regenerate.
