targhooks: i386: rename TAG_SIZE to TAG_BITSIZE
gcc/Changelog:
* asan.h (HWASAN_TAG_SIZE): Use targetm.memtag.tag_bitsize.
* config/i386/i386.cc (ix86_memtag_tag_size): Rename to
ix86_memtag_tag_bitsize.
(TARGET_MEMTAG_TAG_SIZE): Renamed to TARGET_MEMTAG_TAG_BITSIZE.
* doc/tm.texi (TARGET_MEMTAG_TAG_SIZE): Likewise.
* doc/tm.texi.in (TARGET_MEMTAG_TAG_SIZE): Likewise.
* target.def (tag_size): Rename to tag_bitsize.
* targhooks.cc (default_memtag_tag_size): Rename to
default_memtag_tag_bitsize.
* targhooks.h (default_memtag_tag_size): Likewise.
