Value and type pack runtime crash when used in a method instead of free function

[PopFlamingo]

Description

I found a few cases where value and type packs may cause either compiler crashes or executable runtime crashes. This is a simple example where a function has no issue when it is a free function but causes a runtime crash when it is a method.

Reproduction

class Foo {
    init() {}
    func unchanged<each T>(_ value: repeat each T) -> (repeat each T) {
        return (repeat (each value))
    }
}

func unchanged<each T>(_ value: repeat each T) -> (repeat each T) {
    return (repeat (each value))
}

let foo = Foo()


print(unchanged(false, 1, "B")) // Prints (false, 1, "B")
print(foo.unchanged(false, 1, "B")) // RUNTIME ERROR: Thread 1: EXC_BAD_ACCESS (code=1, address=0x0)

Expected behavior

No crash and printing (false, 1, "B")
