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:

*** Configuration mips-sgi-irix6 is obsolete.

and been removed.
* config/mips/irix5.mh, config/mips/irix6.mh: Delete files.
* configure.ac: Remove references to IRIX.
* configure.host: Add *-*-irix* to the obsolete hosts section.
Remove all other references to irix.

* gdb.base/bigcore.exp: Remove references to IRIX.
* gdb.base/funcargs.exp: Likewise.
* gdb.base/interrupt.exp: Likewise.
* gdb.base/mips_pro.exp: Likewise.
* gdb.base/nodebug.exp: Likewise.
* gdb.base/setvar.exp: Likewise.
* lib/gdb.exp (gdb_compile_shlib): Remove mips-sgi-irix* case.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
* mips_pro.exp: Accept either "middle -> top -> main" or
"middle -> main" in the backtrace, because gcc can optimize
tail calls to jumps. Remove setup_xfail for the hppa case.
Add a comment with the original warning messages from PR 3016,
which was filed in 1993, to preserve them for posterity.
"p func1 ()" and note that rests of tests are skipped.
* gdb.base/corefile.exp: Add i*86-*-linux* and m68*-*-hpux*
setup_xfails for "print func2::coremaker_local".
Add i*86-*-linux* setup_xfail for "backtrace in corefile.exp".
* gdb.base/mips_pro.exp: Restart gdb in this test so it isn't
affected by the previous run test.
* gdb.chill/misc.exp: Add m68*-*-hpux* setup_xfails for
"print array () ubyte (foo)" and "print/x array () byte (\$i)"
* gdb.chill/pr-8742.exp: Add m68*-*-hpux* setup_xfails for
"pass int powerset tuple" and "pass modeless int powerset tuple".
* gdb.chill/tests2.exp: Add m68*-*-hpux* setup xfails for
"real write 4" and "real write 8".
* gdb.shill/tuples.exp: Add i*86-*-linux* and m68*-*-hpux*
setup_xfails for "print vs1 after tuple assign 2",
"print \$i after tuple assign 2", and
"print vs2 after tuple assign 2".
* lib/gdb.exp (gdb_test): When a gdb aborts, print a more
meaningful error message and return -1 so the caller can
suppress further tests and avoid a cascade of errors.
