ICU 54 and 56 adds the following formatters1 for currency formatting:

  • CURRENCY_ISO2: ISO currency code, e.g., "USD1.00"
  • CURRENCY_PLURAL3: pluralized currency name, e.g., "1.00 US dollar" and "3.00 US dollars"
  • CASH_CURRENCY4: currency symbol given CASH usage, e.g., "NT$3" instead of "NT$3.23"
  • CURRENCY_STANDARD5: currency symbol, e.g., "$1.00", using non-accounting style for negative values (e.g. minus sign)

This adds support for all four of them to ext/intl, along with tests.
