Log:
  Pull in r217197 from upstream clang trunk (by Richard Smith):

    PR20844: If we fail to list-initialize a reference, map to the
    referenced type before retrying the initialization to produce
    diagnostics. Otherwise, we may fail to produce any diagnostics, and
    silently produce invalid AST in a -Asserts build. Also add a note to
    this codepath to make it more clear why we were trying to create a
    temporary.

  This should fix assertions when parsing some forms of incomplete list
  intializers.

  Direct commit to stable/9 and stable/10, since stable/11 and head
  already have this upstream fix.
