commit db865a1e4453bcdab9151476cf33c52b7b9eceb6
Author: Richard Trieu <rtrieu at google.com>

    Fix for PR21758

    When a non-type template argument expression needs a conversion to change
it
    into the argument type, preserve that information by remaking the
    TemplateArgument with an expression that has those conversions.  Also a
smal
l
    fix to template type diffing to handle the extra conversions in some cases.
