Oops.  I've posted the wrong version of the patch.  This one would
crash should reg_base_offset[regno] be NULL_RTX.  Curiously, this was
indeed the version I had tested on i686-pc-linux-gnu, without any
regressions (yes, I've just double-checked that I did test the
outdated version on x86), but the fix was necessary on another port.
Here's the corrected patch.  Ok to install?
