Reproduction

func foo<T>(_: T, _: T) -> [T] {}

func test() {
  let int: Int
  let int16: Int16
  for _ in foo(int16, int) {}
}

error: conflicting arguments to generic parameter 'Self' ('[Int16]' vs. '[Int]') [conflicting_arguments_for_generic_parameter]
  for _ in foo(int16, int) {}
                         ^
error: conflicting arguments to generic parameter 'T' ('Int16' vs. 'Int') [conflicting_arguments_for_generic_parameter]
  for _ in foo(int16, int) {}
           ^
error: conflicting arguments to generic parameter 'Elements' ('[Int16]' vs. '[Int]') [conflicting_arguments_for_generic_parameter]
  for _ in foo(int16, int) {}
  ^

Expected behavior

A single error in relation to written code: conflicting arguments to generic parameter 'T' ('Int16' vs. 'Int').

Environment

Swift version 6.0-dev (LLVM 48dc0c6fa01ce9e, Swift 2650c285671c227)
