[testsuite] Skip gcc.target/mips/interrupt_handler-[23].c on IRIX (PR target/50580)

[Rainer Orth <ro at CeBiTec dot Uni-Bielefeld dot DE>]

Looking closer into the gcc.target/mips/interrupt_handler-[23].c
failures

FAIL: gcc.target/mips/interrupt_handler-2.c scan-assembler \\t\\\\.cfi_restore 64\\n
FAIL: gcc.target/mips/interrupt_handler-2.c scan-assembler \\t\\\\.cfi_restore 65\\n

and many more for interrupt_handler-3.c, I now understand what's going
on: .cfi* directives are only emitted if dwarf2cfi.c
(dwarf2out_do_cfi_asm) returns true, but if MIPS_DEBUGGING_INFO is
defined (as is the case in iris6.h), it returns false.  Thus, the tests
are meaningless since even the scan-assembler-not tests only succeed
because no .cfi* directives whatsoever are present in the assembler
output.  XFAILing them with dg-xfail-if doesn't work:

XPASS: gcc.target/mips/interrupt_handler-2.c (test for excess errors)
FAIL: gcc.target/mips/interrupt_handler-2.c scan-assembler \t\\.cfi_restore 64\n
FAIL: gcc.target/mips/interrupt_handler-2.c scan-assembler \t\\.cfi_restore 65\n

and adding xfail's to each and every dg-final seems pointless,
especially given that the scan-assembler-not tests only pass by
accident.  I therefore just skip the tests on IRIX.

Tested with the appropriate runtest invocation on mips-sgi-irix6.5,
installed on mainline.
