PATCH [FSF mainline] Fix pattern for store and update for apple-ppc-darwin mixed mode.

[Fariborz Jahanian <fjahanian at apple dot com>]

This is a bug in apple-ppc-darwin in mixed mode (-mcpu=G5) where 
word_mode is DImode.

Routine rs6000_split_multireg_move does not generate expected pattern 
for doing a store and
update and gcc ICEs. This happens when test case is compiled with -O1 
-mcpu=G5 and -funroll-loops.
Fix is to define a new pattern for the mixed mode case and use it when 
sore and update pattern need
be generated. Patch is bootstrapped and dejagnu tested on 
apple-ppc-darwin with -mcpu=G5 and
in default.

OK for mainline?
