I just noticed I must have been dreaming when submitting this bug
report: it's the *32-bit* case that fails, not the 64-bit one.  I'm
attaching the correct dump this time.

cc1 is invoked like this for a 32-bit-default configuration:

$ cc1 -quiet wide-shift-64.c -mcpu=v9 -O2 -fdump-rtl-combine -o wide-shift-64.s
