[PATCH] fixing typo in expr.c to allow proper recognition of complex addresses in some arches.

[Igor Shevlyakov]

I stumbled on a case like this:
If the multipliers allowed for addressing modes are dependent on actual
mode, in some cases compiler
refuses to recognize address as legitimate.
It boils down to this place in expr.c where address_mode is incorrectly
used instead of actual mode.

I rebootstraped and tested on x86_64-linux-gnu but there's no testcase to
see the improved behavior...

Please patch the trunk.
Thanks
Igor

* expr.c (expand_expr_real_1): Use proper memory access mode instead of
address_mode
  in the call to memory_address_addr_space.
