Proposed Fix

Well, I noticed that the first version of this patch caused
a small but measurable decrease of code quality on x86_64,
so I moved the patch to the if (strict_volatile_bitfield_p block,
and used some code transformations to simplify the resulting code
a bit.

I will post this new version for review, after a full boot-strap
and successful regression-test on my ARM target.
