Comment (by Austin Seipp <austin@…>):

 use GHC-7.8.3's values for thread block reason (fixes #9333)

 Summary:
 For now, BlockedOnMVar and BlockedOnMVarRead are not distinguished.
 Making the distinction would mean to change an exported datatype
 (API change). Code for this change is included but commented out.

 The patch adds a test for the threadstatus, which retrieves status
 BlockedOnMVar for two threads blocked on writing and reading an MVar.

 Test Plan: ran validate, including the new test
