    Windows: Bump to GCC 7.2 for GHC 8.4
    
    GHC 8.4 is expected to ship with an updated GCC bindist based on GCC
    7.2.
    
    I am however at this time not updating the crt due to an issue
    introduced in September.
    https://sourceforge.net/p/mingw-w64/mailman/message/36085637/
    
    Unless a favorable fix comes out of the discussion I will just ship the
    old crt with GHC 8.4.
    
    Test Plan: ./validate
