<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Import qualified Prelude in Cmm/Parser.y
In preparation for the next version of 'happy', c95920 added a qualified
import to GHC/Parser.y but for some reason neglected GHC/Cmm/Parser.y
This patch adds the missing qualified import to GHC/Cmm/Parser.y and
also adds a clarifying comment to explain why this import is needed.
(cherry picked from commit fddddbf47d6ba2b1b3b6ec89bd40c8fa020e6606)
