[rs6000] Use VIEW_CONVERT_EXPR to reinterpret vectors (PR 92515)
The new tree-cfg.c checking in r278245 tripped on folds of
ALTIVEC_BUILTIN_VPERM_*, which were using gimple_convert
rather than VIEW_CONVERT_EXPR to reinterpret the contents
of a vector as a different type.

* config/rs6000/rs6000-call.c (rs6000_gimple_fold_builtin): Use
VIEW_CONVERT_EXPR to reinterpret vectors as different types.
