Right now, if I have the following:

struct Foo(pub uint);

I cannot have a static instance of the struct like so:

static FOO: Foo = Foo(1);

I get the following error:

function calls in constants are limited to struct and enum constructors

Edit: This seems like a dup of #17169

fix: Panic in debug profile for tuple deconstruct with arity mismatch

Fixes rust-lang#17585, which doesn't affect daily use cases but quite annoying in development of r-a itself like writing tests.

This PR applies similar approach as in rust-lang#17534, skipping match usefulness check for patterns containing errors
