Hi
This patch back ports r176293 from gcc-4_6-branch to google/gcc-4_6 branch.
BB reorder hides the optimization opportunity, so disable it for the test case.
Tested with
make check-gcc RUNTESTFLAGS="--target_board=arm-sim/thumb/arch=armv7-a arm.exp=pr42093.c"
thanks

This is not needed now. I committed a merge from gcc-4_6-branch
earlier today (I'm merging from gcc-4_6-branch every couple of weeks).
