Rename vshuffle/vec_shuffle to vec_perm.
* doc/extend.texi (__builtin_shuffle): Improve the description to
include the modulus of the selector. Mention OpenCL.
* doc/md.texi (vec_perm, vec_perm_const): Document named patterns.
* tree.def (VEC_PERM_EXPR): Rename from VEC_SHUFFLE_EXPR.
* genopinit.c (optabs): Rename vshuffle to vec_perm.
* c-typeck.c (c_build_vec_perm_expr): Rename from
c_build_vec_shuffle_expr. Update for name changes.
* optabs.c (expand_vec_perm_expr_p): Rename from
expand_vec_shuffle_expr_p.
(expand_vec_perm_expr): Rename from expand_vec_shuffle_expr.
* optabs.h (OTI_vec_perm): Rename from DOI_vshuffle.
(vec_perm_optab): Rename from vshuffle_optab.
* expr.c, gimple-pretty-print.c, gimple.c, gimplify.c,
c-tree.h, c-parser.c, tree-cfg.c, tree-inline.c, tree-pretty-print.c,
tree-ssa-operands.c, tree-vect-generic.c: Update for name changes.
* config/i386/i386.c (ix86_expand_vec_perm): Rename from
ix86_expand_vshuffle.
* config/i386/i386-protos.h: Update.
* config/i386/sse.md (VEC_PERM_AVX2): Rename from VSHUFFLE_AVX2.
(vec_perm<VEC_PERM_AVX2>): Rename from vshuffle<VSHUFFLE_AVX2>.
