Bug 281895 – [JSC] Refactor `Element` in `IntlDurationFormat`

• Status: RESOLVED
• Resolution: FIXED
• Component: JavaScriptCore

[Sosuke Suzuki]

The `Element` struct in `IntlDurationFormat`'s `collectElements` function holds the value of each
    duration unit as the `m_value` field. The `m_value` field is used to pass following two pieces of
    information to `NumberFormat`:
    
    1. The sign bit
    2. The value's type (`infinity`, `NaN`, or `integer`)
    
    The type of `m_value` is always `integer`. Therefore, the `Element` struct only needs to hold the
    sign bit of `m_value` rather than `m_value` itself.
    
    This patch removes the `m_value` field from the `Element` struct and adds an `m_valueSign` field
    instead.
