W/o accurate info provided by vectorizer, the backend can do nothing about this
regression except reverting the patch, that's why i marked the bugzilla ad
tree-optimization component.
Hi:
Here's updated patch which does 3 things:
1. Support vpermw/vpermb in ix86_expand_vec_one_operand_perm_avx512.
2. Support 256/128-bits vpermi2b in ix86_expand_vec_perm_vpermt2.
3. Add define_insn_and_split to optimize specific vector permutation to
opmov{dw,wb,qd}.

So the two functions are not the same (because __m128i is Vector of 2 long long

It is fixed by r11-165.
The gcc constant folding code uses the type_for_size langhook. Use the
default implementation instead of crashing when the langhook is
called. Add a new testcase "prims_struct_eq.rs" that creates trees
that triggers the constant folding.
Also remove the write_globals langhook which was removed
