[Bug target/20813] New: ICE in gen_reg_rtx for 3 spec tests

[janis at gcc dot gnu dot org]

Current GCC mainline fails to build SPEC CPU2000 tests gzip, bzip2,
and mesa on powerpc64-linux with -m64.  The same ICE is seen with
test gcc.c-torture/execute/930106-1.c:
                                                                                
elm3b149% /home/janis/tools/gcc-mline-20050407/bin/gcc -m64 -c 930106-1.c
930106-1.c: In function ‘f’:
930106-1.c:20: internal compiler error: in gen_reg_rtx, at emit-rtl.c:778

have merely exposed a latent bug:
