Log:
    PR target/52624
    * doc/extend.texi (Other Builtins): Document __builtin_bswap16.
    (PowerPC AltiVec/VSX Built-in Functions): Remove it.
    * doc/md.texi (Standard Names): Add bswap.
    * builtin-types.def (BT_UINT16): New primitive type.
    (BT_FN_UINT16_UINT16): New function type.
    * builtins.def (BUILT_IN_BSWAP16): New.
    * builtins.c (expand_builtin_bswap): Add TARGET_MODE argument.
    (expand_builtin) <BUILT_IN_BSWAP16>: New case.  Pass TARGET_MODE to
    expand_builtin_bswap.
    (fold_builtin_bswap): Add BUILT_IN_BSWAP16 case.
    (fold_builtin_1): Likewise.
    (is_inexpensive_builtin): Likewise.
    * optabs.c (expand_unop): Deal with bswap in HImode specially.  Add
    missing bits for bswap to libcall code.

    * tree.h (enum tree_index): Add TI_UINT16_TYPE.
    (uint16_type_node): New define.

    * config/rs6000/rs6000.c (rs6000_expand_builtin): Remove handling of
    above builtin.
    (rs6000_init_builtins): Likewise.
    * config/rs6000/rs6000.md (bswaphi2): Add TARGET_POWERPC predicate.

    * c-common.h (uint16_type_node): Rename into...
    (c_uint16_type_node): ...this.
    * c-common.c (c_common_nodes_and_builtins): Adjust for above renaming.
    * c-cppbuiltin.c (builtin_define_stdint_macros): Likewise.
