Subject: [PATCH] Enable HiPE compile configuration

The ``rabbitmq_server`` role now supports configuring HiPE compilation
of the RabbitMQ server Erlang code. This configuration option may improve
server performance for some workloads and hardware. Deployers can
override the ``rabbitmq_hipe_compile`` variable, setting a value of
``True`` if they wish to enable this feature.
