Delete IRIX support

Browse Source 
This does most of the mechanical removal.  IOW, the easy part.

This doesn't touch procfs.c as that'd be a harder excision,
potentially affecting Solaris.

mips-tdep.c is left alone.  E.g., I didn't delete the GDB_OSABI_IRIX
enum value, nor references to it in mips-tdep.c.  Some comments
mentioning IRIX ABIs may still be relevant and I wouldn't know what to
do with them. in That can always be done on a separate pass,
preferably by someone who can test on MIPS.

I didn't remove a reference to IRIX in testsuite/lib/future.exp, as I
believe that code is imported from DejaGNU.

Built and tested on x86_64 Fedora 20, with --enable-targets=all.

Tested that building for --target=mips-sgi-irix6 on x86_64 Fedora 20
fails with:

 checking for default auto-load directory... $debugdir:$datadir/auto-load
 checking for default auto-load safe-path... $debugdir:$datadir/auto-load
 *** Configuration mips-sgi-irix6 is obsolete.
 *** Support has been REMOVED.
