typeck: Fix const generic in repeat param ICE. This commit fixes an ICE that occured when a const generic was used in a repeat expression. This was due to the code expecting the length of the repeat expression to be const evaluatable to a constant, but a const generic parameter is not (however, it can be made into a constant). 2019-06-09 14:54:28 -05:00			`fn f<T: Copy, const N: usize>(x: T) -> [T; N] {`
