Re: Testing rust 1.56.0

www/seamonkey fails build with rust 1.56.0:
...
      |
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
error: type parameters must be declared prior to const parameters
  --> /usr/pkgsrc/www/seamonkey/work/seamonkey-2.53.9/third_party/rust/packed_simd/src/codegen/llvm.rs:20:54
... (several of this type)

and

error: `[u32; 2]` is forbidden as the type of a const generic parameter
  --> /usr/pkgsrc/www/seamonkey/work/seamonkey-2.53.9/third_party/rust/packed_simd/src/codegen/llvm.rs:20:44
   |
20 | pub unsafe fn __shuffle_vector2<const IDX: [u32; 2], T, U>(x: T, y: T) -> U
   |                                            ^^^^^^^^
   |
   = note: the only supported types are integers, `bool` and `char`
   = help: more complex types are supported with `#![feature(adt_const_params)]`

(again several like these).

It could be just some additional switch, I have no idea.
