Add traceBinaryEvent# primop
This adds a new primop called traceBinaryEvent# that takes the length
of binary data and a pointer to the data, then emits it to the eventlog.
There is some example code that uses this primop and the new event:
* [traceBinaryEventIO][1] that calls `traceBinaryEvent#`
* [A patch to ghc-events][2] that parses the new `EVENT_USER_BINARY_MSG`
There's no corresponding issue on Trac but it was discussed at
ghc-devs [3].
