Update the C data passing conventions in the reference manual since
the signautres of C functions generated by `foreign_export' pragmas

  declaration (@pxref{Using foreign types from Mercury}) will be passed as
  the corresponding C type.

+Mercury tuple types are passed as @samp{MR_Tuple}, which in the current
+implementation is a typedef for a pointer of type @samp{void *} if
+ at samp{--high-level-code} is enabled, and a typedef for @samp{MR_Word}
+otherwise.

  Mercury variables of any other type
  are passed as a @samp{MR_Word}, which in the current implementation
  is a typedef for an unsigned type whose size is the same size as a pointer.
