[commit] Fix compilation warning in procfs.c on mips-irix

While I was building GDB on mips-irix, I noticed a couple of warnings, 
so I decided to fix them.

On mips-irix, the pr_vaddr field is a caddr, and apparently, CORE_ADDR
is not the same size as this type.  So we need to cast it to an integer
type with the same size first, and then to CORE_ADDR.

        * procfs.c (solib_mappings_callback, find_memory_regions_callback):
        Fix a compilation warning on mips-irix due to casting from
        a pointer of different size.

I actually meant to post this patch and wait for a few days before
checking in, but I accidently did the checkin. I'm pretty sure it's OK,
but let me know if not, and I'll revert.
