re PR target/52624 (missing __builtin_bswap16)
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-builtin.def (RS6000_BUILTIN_BSWAP_HI): Delete.
* 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.
