This patch is OK for all branches in my opinion but run it by a RM because
the PR is not formally marked as a regression.
In fact Steven's original patch is slightly better, const0_rtx is valid for all

The above cast should almost certainly have been (volatile int32_t)
The volatile here does not mean anything really so there is no lost info as it
is on a scalar type. So I am going to close this as invalid.
