diff: Bug fix for mercury_memory_handlers.c.

[Tyson Dowd]

Hi,

Here's a fix for the compilation errors that occured in the
(not so) nightly builds recently.

I'll commit this now.

===================================================================


Estimated hours taken: 0.5

Fix a bug in get_pc_from_context that was causing compile
errors on IRIX and Solaris.

runtime/mercury_memory_handlers.c:
	Fix a bug in get_pc_from_context -- it wasn't using the correct
	type (ucontext_t) for the context.
