…uld be specialized
If generic parameter comes from a variadic type declaration it's possible
that it got specialized early and is no longer represented by a pack expansion type.
For example, consider expression -
Test<Int>(42)whereTest<each T>andthe initializer is declared as
init(_: repeat each T). Although declaration basedinformation reports parameter at index 0 as variadic generic the call site specializes
it to
Int.Resolves: rdar://107151854
