[m-dev.] diff: `do_runnext'-related bug fixes

[Thomas Charles CONWAY]

Fergus Henderson, you write:
> runtime/mercury_context.c:
> 	Add `Define_external_entry(do_runnext)', which somehow got
> 	lost when the definition of `do_runnext' was moved from
> 	mercury_thread.c to mercury_context.c.
> 
> runtime/mercury_context.c:
> runtime/mercury_thread.c:
> 	Move the definition of the stack layout for the label `do_runnext'
> 	into the same C module that the label is defined in.
> 
> runtime/mercury_wrapper.c:
> 	Delete an unnecessary declaration of `do_runnext'.

These changes look fine.

Thanks,
Thomas
