Member predicate FormatLiteral::getFormatArgumentIndexFor

Gets the computed format argument index for the nth conversion specifier of this format string (if mode = 2), it’s minimum field width (if mode = 0) or it’s precision (if mode = 1). Has no result if that element is not present. Does not account for positional arguments ($).
