  * Change the calling conventions for unboxed tuples slightly
  When returning an unboxed tuple with a single non-void component, we
  now use the same calling convention as for returning a value of the
  same type as that component.  This means that the return convention
  for IO now doesn't vary depending on the platform, which make some
  parts of the RTS simpler, and fixes a problem I was having with making
  the FFI work in unregisterised GHCi (the byte-code compiler makes
  some assumptions about calling conventions to keep things simple).

    M ./compiler/codeGen/CgCallConv.hs -1 +14
    M ./rts/Exception.cmm -48
    M ./rts/PrimOps.cmm -30
    M ./rts/RaiseAsync.c -10
    M ./rts/Schedule.c -2
    M ./rts/StgStartup.cmm -16
